Government Medical College and Hospital - [GMCH], Chandigarh

Among the 3 aforementioned institutes, ABVIMS Delhi seems to be the best choice in my opinion. A few benefits of joining this college are

• The best part is the PG quota and many students come here for the same reason.
• ABVIMS Delhi offers an altogether different vibe unlike those colleges reeking of rich heritage. 
• The college has a state-of-the-art infrastructure but believes in old-school teaching methodology.
• There are interesting on-campus discussions that make the campus lively.
• The college also enjoys the locational advantage of being located in the capital of India and has many places to explore outside the campus like Talkatora Garden and Sports Complexes, Connaught Place, Patel Chowk, Karol Bagh, Raisina Hills, and much more.

Based on the opinions within the medical community, I will provide some information on these colleges-

1. GSMC- It is a highly renowned college. High rankers in UG and PG entrance choose it for pursuing their medical studies. Clinical teaching is very good over here. 
2. Grant Medical College Mumbai- It is one of the top 10 medical colleges of India. But its fees have skyrocketed recently. The campus is not in a good shape too. However, this college is one of the only 5 colleges whose degrees are approved in Singapore. So if you plan to pursue your PG abroad, a degree from GMC Mumbai will open the doors of Singapore for you.
3. KGMU- It is one of the best medical colleges in North India, and especially UP. It is well reputed, and the campus is really good. The infrastructure is top notch, better than most government colleges. The teachers are decent, and the students are hardworking. You’ll get a good clinical exposure over here. For an outsider though, adjusting to the UP culture might be a little difficult at first.

I don’t know much about GMC Patiala and GMCH Chandigarh, so I won’t comment on these two. 

Make sure to choose a college with hardworking students. Good company will motivate you to study harder and excel in your field. Food and language barriers aren’t much of a problem in the long run. 

With NEIGRIHMS, you will get a better campus, more one-on-one attention, and a comparably easy undergraduate life. On the other hand, GMCH will offer you better patients, cases, more experienced faculty, and better exposure. Guwahati will also offer better connectivity and opportunities. NEIGRIHMS is still in its initial stages. So, there are certain opportunities that you will only get at GMCH, currently.
