Doesn't really matter, as if your goal is to work as a pharmacist it doesn't matter where you get the degree as long as it's accredited, you passed, and you completed the pre-reg things needed to become registered with the appropriate professional governing body. Nottingham I gather is pretty well known for pharmacy but you're going to effectively cover the same material (perhaps in slightly different ways) so just pick the one where you would be happy to spend your 4 years of your degree!
Consider things like costs of living in the area (principally rental prices but also see what the average costs for e.g. transport, food shops, entertainment and suchlike are), facilities offered by the uni that are of interest to you (including non-academic/extracurricular ones), ease of travelling to there and back from your home if you are planning to go home in the holidays, and if there are placements as part of the course, consider the location of placements and travel to/from them (and associated costs!).
At the end of the day the Boots branch hiring a new pharmacist isn't going to care what your university's ranking is. And for hospital based roles in the NHS they may well blind recruiters from your university anyway to ensure no bias!
