I got AAAaa and decided to go to Kent. I never thought it was a brilliant university like Oxbridge, Warwick or Edinburgh, but for the course I was studying (Computer Science) it was very highly regarded. You may ask why I went to Kent after achieving AAA(+ aa), but without A Level Maths to offer, I didn't have a lot of alternatives in terms of Comp Sci at the top uni's.
A lot of the students I met whilst at Kent were clever - most had achieved between AAA and BBC at A Level, but a lot did come to Kent through clearing, after not meeting offers from firm choices such as Exeter, St. Andrews and Cardiff.
Admittedly I did end up dropping out of Kent, but this was because the course didn't suit me, not because the standard of teaching was bad or that the course wasn't well organised; in fact, this was completely the opposite. I would highly recommend Kent - especially to those wanting to study Law (my friends speak very highly of the teaching etc).
Ultimately, I guess Kent is always going to be an upper-third/middle table uni, due to the number of vocational courses on offer and low entry requirements for some degrees. There are some stupid people at Kent, who shouldn't even be at university, but I guess you get that with most places.
