I also found it interesting going through the stats, on unistats after one of the posters in this thread posted the link (

So by comparing say Bristol with Southampton both students come in with relatively similar A Levels though Bristol's students Ucas points is 50 points higher than Southampton students. (400 southamton vs 450 Bristol) Yet by the end of the course, 58 % of Bristol students have a 2.1 and above vs 84% at Southamton. That is 26% more students in Southamton have a 2.1 or more than their bristol counter parts despite getting similar grades at A Level. For Sussex (80%) that is 22% more.This would suggest that Southampton and Sussex add significantly more value to their students than Bristol in the discipline of chemistry. The point is that different universities have their strengths and their weaknesses. I've gone on about Bristol chem, but Bristol Psychology has more 2.1 and First than any other course bar Oxfords, and the same is true for Bristol Biochemistry/molecular genetics.
It would therefore seem a bad decision to say that a whole university is bad. For even the newest of universities have areas where they're a strong relative to other universities. Also some courses at certain universities simply attract the best students, despite having average teaching, something I've experienced first hand.
