I have friends from both Manipal University Jaipur and Sikkim Manipal University. Here is a brief comparison of the two institutes based on their experience. 

• Cutoff: According to the recent cutoff trends, the closing cutoff for CSE at MUJ was 10867 while for SMIT it was 34422. It clearly indicates the difference in student crowd at these two branches. 
• Placements: Placements at both are quite similar. However, considering the location of the colleges, MUJ will be a better option. Big MNCs like Amazon visit the MUJ campus for placements. According to the recent placement highlights the highest CTC offered at MUJ was 42 LPA while it was 24 LPA for SMIT.
• Infrastructure: MUJ has a much better infrastructure than SMIT.
• Faculty: Based on my friends’ experiences I will say the faculty at MUJ is better. 

However, SMIT is an older institute. MUJ was recently established and it will take some time to reach the level of the college experience that SMIT provides.

A few of my friends from MUJ complain about the open book system in the examination. According to them, it is a poor way of conducting examinations in undergraduate as you will eventually need to memorize things for competitive examinations. 

The best choice will be to go for the main campus, i.e. MIT Karnataka. Take any branch that you are getting and you can upgrade your branch to CSE, in the second year. The main campus is far better than these two campuses.

If you're considering pursuing IT, Manipal, Jaipur could be a good option for you as the faculty is supportive and helpful, and the syllabus is somewhat similar to Computer Science with some changes in the 3rd and final year. While the speaker has no personal experience with SRM, Chennai, it's worth noting that branches like CS/IT are rarely dependent on the faculty or college.

In IT, at some point in your course, you will have to learn languages on your own and accordingly code using those languages. So, it's crucial to have a good understanding of the basics and develop problem-solving skills. Keep in mind that the field of IT is continually evolving, and it's essential to keep yourself updated with the latest technologies and trends.

Manipal University Jaipur is the better choice, among these. Jaipur campus has better infrastructure. The departmental labs are well-equipped with latest instruments. Jaipur campus has a more competitive environment. 

Although the placement opportunities are similar for both campuses, due to the central location, MUJ attracts industry giants like Amazon, Wells Fargo, etc. Manipal University Jaipur placements 2021 witnessed the highest CTC of INR 25 LPA. 

Both Manipal University and NIT Warangal are highly regarded institutes with a reputation for imparting excellent education. You can however consider the following points while choosing one between the two

• NIT Warangal is better than Manipal University in terms of placements.
• Manipal University has a better infrastructure than NIT Warangal. 

Had I been in your place, I would have chosen NIT Warangal because placements and job opportunities value more than infrastructure, at least for me. 

However, I am definitely not claiming that Manipal is bad In Fact it’s the best private engineering college after BITS. Moreover, placements are subjective and also depend on the individual as much as on the institutes. With the right mindset, one can avail equal opportunities if not more at both colleges.
