I'm in the exact same dilemma. Both Southampton and Sheffield have given me offers for medicine and I don't know which to firm. Ranking wise, they're quite similar. Sheffield is much closer to home than Soton of course, but I don't like the fact that Sheffield's a city university. Soton has a much prettier campus and that's something I really care about. But I guess after I go to the offer holders open day for both I'll be able to make a decision... :/
