I would personally recommend you choose AIIMS Raipur over Pt. Jawahar Lal Nehru Memorial Medical College. Although there are many reasons that have gotten me to this conclusion, I will list down the core reasons that will help you make up your mind.
Pros-
AIIMS Raipur is a central institute that lays more emphasis on quality education.
You don’t have to sign any bonds
You get to meet a better crowd. This is because AIIMS Raipur constitutes the cream of medical students. Whereas in Pt. JNM, people who are not selected in other colleges usually get admitted.
The infrastructure is equally good in both colleges. But the hostel facilities are horrible in Pt. JNM.
The DKR super specialty hospital is the pride of AIIMS Raipur.
AIIMS Raipur is house to a full-fledged sickle cell research institute
AIIMS Raipur also has an advanced Cardiac Institute and a new regional cancer center building
Cons-
The patient load at Pt.JNM is comparatively less than that at AIIMS Raipur This helps you protect your quality over quantity agenda. This is also a must needed skill for every doctor.
Pt. JNM has an extensive aluminum base whereas AIIMS Raipur lacks in this aspect.
The faculty at AIIMS Raipur is understaffed. Whereas at Pt.JNM the faculty is experienced and also satisfies the MCI criteria.
I hope the points helped you reach a decision.
