Comparably NEIGRIHMS is better. However, both of these two institutes have their advantages. 

NEIGRIHMS: 

• It has a virtual dissection table. Other than one or two medical colleges, you can’t find this facility anywhere in India.
• As their student intake is not high, the student-teacher ratio is better. You will get more personal attention from teachers. 
• The campus is clean and quite beautiful.
• The internship salary is more. 

GMC: 

• It has more faculty.
• You will have access to PG coaching centers like Dams. As it is situated near the college.
•  It also offers better exposure. 

NEIGRIHMS has improved a lot in a very short time. The healthcare quality offered on campus can’t be compared to anywhere else.
