Dear aspirant, 

If you are looking for gate after your graduation then i would suggest you to go for JSS as they are less strict for attendance as compared to Abes so that yoi can prepare for gate in your semesters. If you are looking for placements then also i would suggest you to go JSS because it has better record of placements as compared to the other ones.

I'm telling you the facts based on the information i have gathered on the net. I'm not a student of any of these colleges. 

Hope this will help you. All the best..!!
