There is absolutely no benefit in getting a seat through All India counselling.
In fact state counselling has a benefit of fees concession for OBC and SC/ST candidates ( a concession of near about 9000 rupees for obc candidates) . You don't get this benefit through All India counselling. Though I agree that the All India counselling is hassle free ( being online) but I heard that this year state quota counselling will be conducted online as well .
Please don't expect to get a special treatment in college just because you got a seat via All India counselling. Things don't work that way in a medical college. There is no discrimination on the basis of your rank or mode of counselling.
