Warwick. It's only taken forty years to build up an amazing reputation and it just seems to get better and better. They have great facilities too - not much in the way of pretty old buildings for sure, but much more in the way of stuff for students - the biggest arts centre outside London, the best SU facilities in the country, top notch sports facilities, and so on. The people who slag it off tend not to have spent much time there (if any at all) but to my mind a combination of brilliant campus + great reputation = top choice.
