Which is better, RVCE ECE, MSRIT CSE/ISE, or MAIT (Delhi) CSE? I am interested in coding.

MAIT CSE is out of the league. Now b/w RVCE ECE and MSRIT CSE/ISE, both are great options because placement wise they are pretty same. But ECE in RVCE is hectic and strict compared to other branches, if that concerns you then go to MSRIT. But if you want a bigger campus, facilities, clubs, activities, fest etc. and overall a better peer group and tag, then you should prefer RVCE.
