This is a very common question every one will get. But i could suggest, first make a background check on the college, and then choose the one which you feel better.

The important things you should check to join in any Engineering college:

1. Lab Facility: Check the lab facility first, because in the Engineering you will have many subjects to read, but if you do lab well you can understand even more better than your lectures teach you in the class room.
2. Autonomous/Affiliated: This plays a important role on the subjects you read and makes big impact on your Engineering certificate. Why i said this is, during job searching time, when you go for interviews there are some MNC companies, who care much about the type of college you studied.
3. Placement Assistance: Check with preciously studies students, how that colleges bringing placements and one important thing here is what type of jobs they are bringing, and what type of jobs did the previously joined students working on.
4. Culture: Check how the college system works. Strict, Time punctuality, attendance etc.

Hope this helps you.

All the best!
