Hello Aspirant,
Three of  the colleges mentioned by you are good and it depends on you, to choose which college
If your concern is about quality of education then go with the college which have best teaching faculty ,
Goa medical college is one of the oldest Medical college and Hospital in Asia,
Govt Medical college, aurangabad is affiliated to MUHS,
NSCB is the oldest medical college in the state of madhya pradesh , admission is through pre - medical entrance exam .
Selecting a college should also include it's infrastructure, hospital strength, distance and also facilities, and you would know about these when you personally visit those college's and be aware of the environment .
I wish you good luck ,
All the best !
