As I've said before, i really think it's important to consider which course will suit YOU best.
As far as the uni's are concerned, they both have good reps - It really makes no difference where they feature in league tables etc.
Both cities (I live in Manc) have their ads and disads.
Notts is campus based, on outskirts of city (10 mins bus), whilst Manchester central and less of a true campus. Both have dodgy areas, and I would say student areas in Manc worse than those in Notts.
As far as social life is concerned, both are great - more clubs in Manchester, but I prefer the 'bars' of Nottingham.
Think about how far from home you want to live?
Do both guarantee accommo to 1st years?
Pharmacists at Notts spend quite a lot of time in lectures with medics in 1st year. Therefore spend some of their time in medschool, and some in pharmacy on the main campus.
