I can give you a gist based on which you can decide which one suits your interest.

In AIIMS bhubanaeshwar the administration is strict. They conduct frequent tests and are strict about their course curriculum. The campus is beautiful and very well developed. The airposrt is 15minutes away from the main  campus and the students studying there are from every corner of India. Bhubaneshwar itself is an amazing place to live in. The only catch is you might have to study oria as one of the courses but at the end it will be a boost and useful.

The bhopal branch is equally good in academics but the administration is not as strict there. The language barrier wont be teher if you are a hindi speaking candidate. The climate here is more pleasant and moderate. The sports facilities are nt as good as bhubaneshwar campus. The relationships between seniors and juniors is better here and it exceeds bhubaneshwar branch in terms of fests.

Aiims jodhpur, however , surpasses both the institutes specially if you are a vegetarian. It is also friendlier to hindi speaking people. The sports at AIIMS Jodhpur is better than others.Hostels are well maintained with separate room per student. The labs and research facilities are the best here.

MMC Chennai- The hostel is comfortable but the food and language prblem is there if you are a hindi speaking north indian. The academic pressure exists making the life a little dull exceptfor the cultural events. There rae a lot of students in both ug and pg because of which forming a student teacher relationship is almost impossible. It is the best college in Tamil Nadu but the fact that most teachers prefer tamil and the studies pressure is a bit too much might be a problem for some.

Hello,

All these medical colleges are among the best in the country, as all have great academics, devoted faculty and good infrastructure and educational quality and peer group.

The only factor different is their locality, you can opt for any of these on basis of your convenience(on basis of factors like distance from home, food, local language etc). However aiims  has a brand name but mmc too is among the best colleges of the state.
