Since you haven't written from which branch perspective you are asking, I am taking the liberty and writing from computer science student perspective.

I would rank PESIT number-1 followed by RVCE and Manipal.

I'm writing below for PESIT.
The quality of teachers is good and classes do happen (no mass bunk :P)! The quality of assignments and programming assignments in general is good and deadlines are taken strictly (You will be ready to combat pressures of corporate world)

You will have good industry exposure, with people from corporate society visiting the campus and conducting workshops to offering internships. They actually have an in-campus company called "Ordell Ugo" which conducts proper corporate level interviews and offers jobs/internships and they are solving some interesting problems.

In between all the studies they have fun too. We had something called "extended working day" activities which had antakshari, sack race and dumb charades which was on wednesdays (might have changed now)

And placements no doubt is the best. Almost all the companies in Bangalore visit the campus.

Hope this helps.
