to be fair, york and exeter are very similar as angelil has said. exeter is 17th, york is about 10th. both are in historic cities, both are older universities, both have a similar sized student population, similar research income, similar high rankings in traditional departments, and both ask for high grades at a-level. york has more value on tsr because people on tsr read more into the league tables than they should, but in all seriousness, unless you are applying to amazingly competitive city jobs, the brand name doesn't make a great difference. when i was applying to universities i could get into york with ccd at a-level, so the current trend towards york really is a phase rather than some ultimate general truth about superior quality. now, if you where interested in something like neuroscience, and you asked about the difference between ucl and exeter, then a huuuuuuuuuge difference exists, but you are not asking for somethign so specialist.
