Hello Drashti

I think the first thing you should look for in a college is academic and ECA .

These both colleges have lots of similarities but I'd talk about dissimilarity.

Karnavati college fees is around 18LPa whereas that of Manubhai patel college is 16.04 LPA for general and for Management quota is 29 LPA

Karnavati college has its own gym while manubhai patel didn't.

Karnavati college was established in 2005 while manubhai patel college was established in 2000

These are some of the dissimilarity final decisions is yours

I hope it helps
