Is Exeter University Overrated and Snobby?

So I'm still waiting to hear back from The University of Exeter to study Politics and Sociology (hopefully with a year abroad which for me is a big deal!), what attracted me to the uni is that it seems like a pretty cool place to live, the campus is beautiful apparently, and the Exeter Politics department is consistently ranked in the top 10 in the country (although doesn't do as well on international league tables.) I was pretty convinced that if I got an offer there then I would definitely go, but ive done some research and apparently the Uni has a reputation for being snobby and abit elitist? Does anyone know if that's still true of Exeter? Also many have said Exeter is overrated and that over the next few years it will probably start slipping down the league tables, although im probably focussing too much on them anyway. It seemed like a perfect choice until I read all that. I also have an unconditional offer for Sheffield btw, would I be crazy not to accept that?
