Go for it! Getting into any pharmacy school is really good. Although I don't go to portsmouth, I know people who have gone to portsmouth and gone on to work in big london hospitals and even industry. In contrast, there are people I know from Nottingham Uni who have gone and worked for independant pharmacies.
It really depends on you as a person. Also, how much you are willing to work. In terms of your statement, it is true. The gphc regulate all pharmacy courses, so the teaching is essentially the same!
