Trust me there is no right answer to your question as the choice of the institute is a matter of personal inclinations and goals. However here are a few points you would like to consider before selecting your college

• Academically, the quality of education and the research facilities available are similar in all the aforementioned institutes and so you choosing one over the other will not compromise your education.
• The primary factor should be location. Here there are 2 things to consider proximity to your home and the kind of college life you want. If you want a tranquil and calm life go for AIMS Rishikesh but if you are a city lover, go for Seth GS.
• Infrastructure-wise, AIIMS definitely gives an edge to Seth GS. The modern campus, with top-notch equipment and hostel facilities, offers a more comfortable and modern college life than an old institute like Seth GS. 
• Being a central institute, AIIMS offers more exposure to diverse cultures and a mixed student body.
• AIIMS Rishikesh follows a total MCQ exam pattern making it easier for NEET PG preparation. 
• The most lucrative aspect of AIIMS is the tag associated with it. You will forever be honored for being a part of an institute of national importance.
• There is no bond policy in AIIMSwhereas Seth GS has one.

Now it depends on you to decide which factor attracts you and which factor you are ready to overlook. Once you have weighed all points only then you can arrive at a wise decision.

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. 

Here are a few parameters to compare GMC Mumbai and VMMC-

• Location- Both the cities are top-tier, but I would suggest going for Delhi. It offers better PG coaching facilities.

• Internal Reservation- VMMC offers internal PG reservations, whereas GMC does not. 

• Clinical Exposure and Faculty- VMMC offers much better clinical exposure and faculty.

• Paraclinical Academics- In this regard, GMC is much better than VMMC.

• Close to hometown- If you are a North Indian, VMMC will be much more accessible from your hometown.

• Brand Value- Both the colleges have equal brand value.

• Hostel facilities and campus culture- In this regard, VMMC is a better choice. 

Both GMC Mumbai and VMMC are good institutions. However, VMMC is a better choice according to me.

According to the reviews online by the students of these colleges, here’s what the ranking seems to be like:

• KGMU has mostly been ranked among the top 5 institutions in India. It usually maintained its place in rank 2 or 3. This institution is 125 years old with proper educational experience.
• AFMC is a very disciplined institution with strict rules and codes of conduct, as it has direct affiliation with Armed forces. Though being well reputed, in academics and exposure it might lag behind.
• MAMC, Grants Medical College (GMC) and IMS BHU are at a similar level.
• Some students claim MAMC to be slightly better than AFMC. 
• GMC is very popular in and around Maharashtra.
• IMS-BHU is autonomous; it has the reputation of BHU tagged along which is beneficial.
• CMC is amongst the oldest medical colleges, but their severe lack of proper facilities in this college and political disturbances have tarnished its reputation.

Therefore it is suggested you either go for KGMU or MAMC, as they will provide you with the required exposure and opportunities.

This majorly depends on the student’s choice and what they will prefer. Seth GS and Grant Medical College (GMC) are both good institutions. Here’s mentioning some facts analyzing which you can make your decision.

• GMC has the largest campus in Maharashtra, also it is one of the oldest colleges in India.
• They offer both boys and girls hostels. They also have separate common rooms.
• The hostels are spacious and offer both single and double occupancy rooms.
• Unlike other medical colleges, many cultural events, festivals, extracurricular activities, etc. take place here quite frequently.
• Seth GS is comparatively stricter and prefers discipline and punctuality.
• Most of Maharashtra’s top ranking students usually go there.
• Students outside Maharashtra tend to prefer GMC.

As mentioned by most of the students that GMC has better academics, facilities and co-curricular activities, it is suggested that you go for GMC rather than Seth GS.

This choice majorly depends on the student and his preferences. 

Seth GS:

• If you prefer studying a lot probably most of the time then opt for Seth GS. 
• They have a highly qualified staff and caters to KEM Hospital. 
• You will be studying amongst some of the brightest minds. 
• The hostel and accomodation facilities are the only problem, due to its location.

GMC:

• If you want to enjoy your college life, Grant Medical College (GMC) will be good for you. 
• It has the largest campus in Maharashtra. 
• GMC conducts the best cultural fests and events, be it sports, art or academics. This provides great exposure. 
• The staff here is also highly qualified just like KEM. 
• Students here tend to lean towards the extracurricular activities more than the studies. 
• The campus has 2 boys hostels and 1 girls hostel enough to provide lodging for all the students who apply. 
• The hostel provides facilities like hot water, pure drinking water, beds, tables, etc. 

Most people will claim that KEM is better for your career. But at the end of the day you also need some extracurricular activities to engage in and avoid the monotony.
