Hello,
It is difficult to compare two colleges of such stature. Both are equally good colleges, and as you stated about the fee structure so that is more or less the same for both according to previous year just the mess and hostel fees is what differs. Now it depends on what basis are you asking if you want to go for a government college which is also older and has more experienced faculties then GMC is better other than that ACMC is ranked among the top 25 colleges in India. So, it depends on your choice.
Hope it helps.
Good luck.
