Madras Medical College is much better than Bangalore Medical College. It is also more reputed. However, if you aren’t from South India, then choosing Bangalore Medical College will be better. If you know English and Hindi, you can easily adjust at Bangalore. But you will need to learn Tamil if you are going to stay in Chennai. 

Kolkata Medical College and Madras Medical College both are well-reputed medical colleges. Here is a comparison of the institutes. 

• Both institutes offer decent academics. But due to immense political pressure in Kolkata, there are routine interferences.
• There are multiple hostels at both medical colleges. Madras Medical College Hostels are under MCI scanner, so cleanliness is a priority there. At Kolkata Medical College, only the Main boy’s hostel is under MCI scanner. 
• Both colleges boast of having one of the best faculties in India.

Both medical colleges were established way back, thus the infrastructural facilities offered are similar.

Among these colleges, Madras Medical College is the best option. It is one of the oldest medical colleges in India. It offers huge case studies due to the patient load. The teaching faculties are great. The infrastructure of the institute is quite good. As the institute is located in the capital, it is more or less like a private medical college. 

After MMC, the 2nd best option is Stanley Medical College followed by Madurai and Thanjavur. You will get to witness huge case studies at Thanjavur as it serves as a single medical college for three nearby districts.
