Priorities of colleges which are better are:

Nit Warangal > Iiit kanchipuram > nit puducherry

While in courses it will be ece >eee > biotechnology

But when going with ur specifications and viewing average package,the order will be:

1.iiit kanchipuram ece

2.nit puducherry Eee

3.nit Warangal bt

And it solely depends on your passion for that subject too!

Good luck!
