If that is the case, then my recommendation would be as follows. Everywhere on that list is pretty sound, but I'm of the opinion that a set of UCAS choices should always include at least one slightly more 'aspirational' choice - i.e. somewhere the standard offer might be a bit higher than you think you'll get. In the list of 'aspirational' departments, I'd expect to see places like Oxford, Cambridge, Imperial, UCL, Bristol, Bath, maybe Warwick. I'd say that Manchester is the only one on your list that strikes me as better than the rest.
