Your answer entirely depends upon what your requirements are. 

• Two essential things that you would require as a CSE student most of the time are a good internet connection and a laptop. 
• Another truth is that just like any other college, you would have to surf YouTube to learn new stuff. This has nothing to do with the faculties. Nevertheless, the quality of teaching in institutes of national importance like IIITs is far better than in private institutes. 
• As far as the new IIITs are concerned, they would ensure you are given the finest of education along with decent placement packages. But at these institutes, you will not have many facilities for extra-curricular. 

Private colleges do offer good infrastructure and campus life but the teacher to student ratio, the quality of education generally do not compensate for the huge amount they charge. But if you look at IIITs, the student-to-teacher ratio is fine. 

Private colleges are always a gold option for the "fun" factor. But if you are looking for fine education quality, IIITs should be your first priority.

Just a side note, this doesn't mean that IIITs won't include the "fun" factor you're looking for. It simply won't have that great of an experience overall. Plus the infrastructure would not be very impressive either. But the quality of education you would find here would be unmatched. 

I have friends from both Vidyalankar Institute of Technology and KJ Somaiya. Based on the conversations I had with them, I will suggest you choose KJ Somaiya for a CS degree.

Here are some of the reasons why you should prefer KJ CE/IT over Vidyalankar CE /IT.

• KJ Somaiya is an autonomous institute. So their course curriculum is quite flexible. 
• Vacations will be quite long. You can utilize this time to do internships in some IT firms. 
• The CS and IT department of KJ Somaiya has amazing CSI and other councils working for them. 
• KJ Somaiya has a vast campus. The sports facilities offered at the institute are also quite great. 
• The placement average for KJSCE is 100% for CS IT branches. As it is an autonomous institute more recruiting companies visit the institute for placements. 

Vidyalankar is not a bad choice either. Both colleges have their own advantages. Here is a brief comparison of the two institutes. 

You should do your own research on the institute and choose according to your convenience.

The ranking for JUET and Manipal, Jaipur by NIRF is 86 and 151. However, choosing the best course in a specific college depends upon your level of interest, eligibility, cut-off rank, placement cell, etc.

Sikkim Manipal Institute of Technology seems a better choice to go with. Having cracked the SRM University Entrance Test, some of my friends still chose ECE with Sikkim Manipal Institute of Technology. SRM has an edge in terms of placement opportunities due to it being located in the city.

Few specific Highlights about Sikkim Manipal Institute of Technology –
