Hi Smruti 

Vinayaka Mission's Medical College was established earlier than Shri Satya Medical College but SSMC is a better college than VMMC.

SSMC has 150 mbbs seats and VMMC has 100 .

Fees structure of both the colleges are almost same.

Kanchipuram is an Ancient city ;full of temples and karaikal has temples but beaches too.

I hope this information proves hrelpful to you.

All the best
