Both IIT Delhi and IIT Kanpur are well-respected institutions in the field of engineering and technology. They are both ranked among the top engineering colleges in India, and they have a reputation for producing successful graduates. However, while choosing between the two you can consider the following aspects 

1. Ranking: According to NIRF rankings, IIT Delhi stands in the second position while IIT Kanpur is in fourth. So IIT Delhi enjoys a better reputation and preference rate than IIT Kanpur mainly because of its location.
2. Course: IIT Kanpur offers an abundance of courses to choose from. It has 8 B.Tech programs; 13 M.Tech programs; several dual degrees; B.Sc and M.Sc; Ph.D. programs and M.Des. (Master of Design). The courses are well-structured with a better grading system than IIT Delhi and thus in this aspect, IIT Kanpur is surely the winner.
3. Placements: The placement scenario at both the IITs are somewhat similar with IIT Delhi at a slight advantage owing to its location. The table below gives the statistical differences between placements of the 2 institutes 

       4. Alumni network: Both IIT Delhi and Kanpur have equally good alumni like N. R. Narayana Murthy and Manindra Agrawal from IIT Kanpur and Sanjay, Binny Bansal, and Chetan Bhagat from IIT Delhi.

       5. IoE: One interesting aspect that sets IIT Delhi apart from IIT Kanpur is its Institute of Eminence (IoE) Status, under which the Institute can make its own decisions regarding course structure, infrastructure, fees, etc. This is unique and only IIT Bombay and Delhi are the IITs that enjoy this status as of now.

Both the IITs are unique in their way with their strengths and weaknesses. Ultimately, the ‘better institute’ is more of a personal choice and depends on many factors. If I were in your place, I would have certainly taken IIT Delhi mainly because of its prime location.

This is a very common debate sparked among aspirants who aren't sure of which field to enter that will shape their career in the best possible way. While the final decision can be taken by the individual itself, a few basic points of comparison below might help you make a more informed decision.

• Engineering covers a short duration of 4 years while Medical requires a long commitment of 6-7 years.
• Engineering is no doubt easier than medicine and has more practical concepts while medical studies require mugging up of thick books 
• The job opportunities in Engineering are highly competitive due to the large supply whereas medical professionals are in high demand due to short supply
• Job stability is higher for medical professionals than engineers
• The working environment of medical professionals is very challenging and unpredictable whereas engineers have a relatively smooth working environment. 
• Very few and demanding higher study options are available in the medical field whereas engineering has a lot of higher study options like master's, Ph.D., and MBA
• Engineers usually work under other higher authorities while medical professionals set up their private practices quite early.
• There are more options for engineers to settle abroad than Medical professionals.
• As an engineer, you keep learning and upgrading your skills throughout your life while doctors learn once and spend the rest of their life practicing what they have learned.

Both fields offer contrasting opportunities and lifestyles and ultimately you need to choose the one that inclines with the expectations of your future.

Yes, irrespective of the branch, choosing IIT Delhi will always prove to be beneficial for you. IIT Delhi has ties with many big firms that visit the campus for placements and offer great packages irrespective of your branch. One needs to be proficient in DSA and other computer science core subjects such as OOPS, OS, DBMS, and Computer Networks. A good grasp of these will fetch you a high-paying job no matter which branch you belong to in IIT Delhi.

Although most companies that visit IIT Delhi also visit NIT, your IIT tag will always fetch you extra benefits and no one can deny that. For instance, the same role offered to an IITiand will have more salary than that offered to a non-IITian.You can easily switch roles and fields given the brand name of the institute you are associated with. IITians even have more opportunities for higher studies in Foreign countries than non-IITians.

IITians especially from Mumbai or Delhi are always given preference over non-IITians hence it is advisable to go for IIT Delhi in any branch.

I don’t think anyone choosing IIT Delhi over any other engineering college has made a wrong decision given the opportunities and life experiences that come with it. While both are crucial, your choice of Institute is more important than your branch. 

Here is a friend's journey for your reference l was a BTech student (Civil) at IIT BHU with a rank of 3600. 

• First, he completed a Nanodegree program from Udacity in Self Driving Cars and Machine learning
• Next, he worked as a Derivative Trader in Future First where he performed Machine Learning and Deep Learning algorithms.
• After gaining great experience and exposure he joined Quantela Inc for 2 Years where he worked as a Data Scientist.
• Today, after a lot of job switches and immense experience he is working at Derq in Dubai as a Machine Learning Scientist and doing Online MS from Georgia Tech University in Computer Science.

This journey of a 7-pointer Civil Branch student to a high-tech CS company proves that branch does not matter in the end. He made the most of his campus life and kept struggling to switch his branch and eventually succeeded. That being said, you have made the right decision as only IIT Delhi can give you the right set of opportunities and exposure and not DTU.

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.

The curriculum of Engineering Physics at both IIT Madras and IIT Delhi is equally instructional and well-structured. The demand for this discipline has witnessed a steady increase over the past few years. 

If I had to choose between IIT Delhi and IIT Madras, I would have opted for the latter. This is because

• IIT Delhi lacks in terms of technological instruments and its infrastructure is not on par with IIT Madras yet. 
• The hostel facilities are very substandard and the quality of food served in mess is pathetic in IIT Delhi
• The sports facilities are highly lacking and the infrastructure is also average
• There are illogical restrictions on the use of the Internet.

In my opinion, unless it’s a matter of locational preference, go for IIT Madras over IIT Delhi any day. You won’t be able to enjoy your college life to the fullest here.
