Hi Chetana,

All the colleges that you have mentioned are best for pursuing engineering.

Walchand is a Govt college whereas all others are private colleges.

So the fees for Walchand will be lesser as compared to others.

Location-wise, MIT, PICT, & SPIT are better. MIT has now become a private university and its fee is quite high, nevertheless, it has maintained its reputation.

PICT has only branches and is known for CS. 

Both MIT & PICT are well established as compared to SPIT established in 2005.

All the Best!!
