The choice of Institute or even the choice of the branch depends on where your inclinations lie. Still, if I would have been in your place, I would have opted for either IIT Roorkee Electrical or Electronics. Here are a few points that justify my inclination towards IIT Roorkee in general and these branches specifically

• The placement scenario of both the branches is excellent with the highest package of both the branches around INR 1,06,00,000. The average packages are well above 15 LPA.
• Both branches provide excellent exposure in terms of opportunities and knowledge 
• The location of the Institute close to the IT hubs like Gurugram, Noida, and the other cities of NCR helps establish industry relations and improve placements tenfold
• The college has a rich coding culture with platforms like SDS Labs, PAG, and IMG making it possible to inculcate coding skills
• The TPO is very responsible and encourages infant companies and startups to offer internship opportunities to its students.
• The overall infrastructure of the campus is decent with hygiene maintenance and basic facilities. Being close to the Himalayas, you can occasionally plan trips also.
• The hostel and food facilities are also good despite the hostels being very old.
• IIT Roorkee has the oldest and strongest alumni network of all the Engineering colleges in India

All in all, the Institute and the branches are much coveted and should be preferred over the other options you have.

Comparing IIT Bombay’s Electrical with IIT Delhi's CS is like comparing the two best things preferred by different people. No department is better than the other because the sole purpose of the department is to cater to the needs of people with different inclinations. 

With all honesty, both courses have their unique aspects. The courses and the job prospects of both the branches are different yet excellent. An electrical engineer works with top-notch technologies like microprocessors or communication systems while a Computer Engineer is talented in using computers in fascinating ways. 

Institute-wise, both IITs are excellent and no college is better than the other. Both institutes are the best ones that could go for and are the most coveted among Engineering aspirants. The opportunities, education, and placements offered by these 2 IITs are second to none. You won’t regret choosing one over the other.

With the two best choices at hand, go for the one that solely matches your preferences and doesn’t be driven by society's standards.

The key differences between a summer internship in CS at IIT Bombay and Delhi are:

• IIT Bombay has a higher intake of CS interns than IIT Delhi 
• The CS program is much better structured in IIT Bombay than Delhi
• IIT Bombay internship projects focus less on research and more on what you have studied whereas IIT Delhi has a higher research-oriented approach.
• The selection process for an internship is easier in Bombay than in Delhi
• The peer group is much more versatile at IIT Bombay as it welcomes students from diverse backgrounds thus enhancing your learning experience.

Some common aspects of internships offered at both the institutes are

• Both the institutes are said to offer the best internships in the country
• Most interns selected in both the colleges are in their 2nd year 
• Both institutes have a location advantage 
• The pay is similar 

In reality, the internship programs of both the institutes give an edge to each other so one can choose based on his personal preferences like location, etc.

There are two sides to every coin. Similarly, there are many reasons why one must choose IIT Delhi over IIT Mumbai and vice versa. To make it further understandable, I have listed some common pros and cons of IIT Delhi

Pros

• You are in proximity to the capital city 
• It’s easy to prepare for some other exams also apart from Engineering like IAS
• Hauz Khas village in itself is an absolute treat to the eyes
• Being in Delhi makes it possible to go for road trips to Jaipur, Chandigarh, Lansdown, Rishikesh, Dehradun, Agra, etc.
• The Delhi Metro makes commuting quiet easy
• There are many places to explore and hang out with your friends in the vicinity of the campus.

Cons

• CS department of IIT Bombay is way better than IIT Delhi offering a plethora of diverse courses.
• The campus of IIT Bombay has more natural landscape and greenery in comparison to IIT Delhi. This enhances the climate and overall ambiance inside the campus 
• Unlike IIT Delhi, the hostel facilities are much better at IIT Bombay while Delhi hostels are overly crowded.
• Delhi faces extreme climatic conditions whereas the weather of IIT Bombay somehow remains the same throughout the year.

I leave it to you to weigh the pros and cons accordingly and make an informed decision.

People usually choose one from IIT Bombay or IIT Madras over the other because of geographical reasons and not academic reasons. 

Academically, it’s the course you are choosing that decides which Institute is best for you. As far as CS is concerned, the program has equal rigor and dynamism at both institutes. However, IIT Bombay has a slight advantage over IIT Madras considering the academics.

If you are concerned about the culture, both institutes offer great ambiance. It’s just a myth that North Indians find it difficult to settle in IIT Madras. Hindu is spoken in almost all IITs and only food might disappoint you a bit. However, culture is a secondary aspect and what matters is the quality of education offered at that Institute. This varies from course to course.

Both institutes will help you create amazing memories and offer an excellent college-life experience. So, the best college for you will depend on your individual needs and preferences.

One can consider aspects such as location, campus culture, and specific programs while making their decision.

NIRF rankings are not the sole factor that determines an institute's worth and credibility 

Usually, rankings systems evaluate an Institute based on aspects such as international students, international faculty, and research which don’t matter much for a UG student.

Even without the JEE, IIT Bombay has always been a much more preferred IIT than Madras mainly because of its location advantage and thus excellent opportunities.

IIT Bombay is preferred because of herd mentality as most JEE toppers consider only IIT Bombay worthy of their rank. It’s like because that has been the usual trend, they have to follow it. In reality, IIT Madras has its share of toppers though the numbers might be less in comparison to IIT Bombay.

While academically, both institutes give tough competition to each other, there are certain minor aspects that distinguish them and make IIT Bombay a much more preferred choice than IIT Madras.

Climate: Although both Mumbai and Chennai are particularly known for their hot climate, IIT Bombay still has moderate climate conditions in November and December which are hot months in Chennai.

Food: Chennai has a limited variety of cuisines specializing mainly in South Indian food. The North Indian food is just average and for a better taste, you will have to go to an expensive restaurant. Mumbai on the other hand satisfies all taste buds from idli, vadas to Butter chicken. Even the fast food is much better than in Chennai.

Job opportunities: While both Mumbai and Chennai offer amazing job opportunities, Bombay definitely covers more sectors. IT and Automobile job opportunities are in abundance at IIT Madras. IIT Bombay being the commercial capital has opportunities in the corporate sector. It also has the biggest port nearby.

Cost of Living: Chennai is way cheaper than Mumbai in terms of food, restaurants, recreation, lodging, etc. However, traveling expenses are equal or cheaper in Mumbai.

Cleanliness: Chennai is cleaner than Mumbai and so is its seawater. Mumbai has a lot of slums which lowers the cleanliness factor a bit. New Bombay is however very clean.

Public transportation: Mumbai has better transport facilities than Chennai. In Chennai, buses are crowded but less crowded than trains. Taxis, trains, and the Metro are very expensive. In Mumbai, trains are more crowded than buses. Metro is the most preferred transport in Mumbai. Taxis and autos are limited but cost average.

Exploration: Chennai has many beaches, and male and movie tickets are also cheaper than in Mumbai. Mumbai has Juhu, Bandra, the Gateway of India, and many other famous spots. It has theme parks and pubs in plenty too.

In short, both IITs have their own strengths and weaknesses with IIT Bombay having a slightly higher advantage compared to Madras.
