I think NIT Surat Electrical is better than RVCE CSE as NIT is reputed college anywhere you go you have advantage of study from NIT and NIT have good minded students and strong alumni network.If you have interest in coding you will  join coding club.

Both are the good colleges difference is only That RVCE is private college & NIT Surat is Government you can choose as per your convenience.
