Which would be better, VIT CSE or NIT Puducherry electrical engineering?

VIT CSE is better in terms of placements, industry exposure, opportunities, and many other things as compared to NIT Puducherry Electrical. According to the recent placement highlights of VIT, the average CTC offered was 6 LPA and the highest CTC offered was 75 LPA. 

On the other hand, NIT Puducherry is a Govt. college. It changes less course fee. For a B.E degree, NIT Puducherry charges around 2.17 lakhs, while a B.Tech from VIT will cost around 8 lakhs. The peer group at the institute is great. You will also have the NIT tag with your degree. That is certainly a perk of pursuing a degree at NIT Puducherry. 

However, you should choose the institute based on your interest. If you like coding go for VIT CSE, or if you like basic sciences more than NIT Puducherry Electrical Engineering will be a better option for you.
