2 things
When it comes to your reasons and going to Aston would be closer to home and family and the like, ask yourself do you want a university experience where you go home every weekend believe me go home for the weekend and I personally feel you miss out on a lot. For some people (such as myself) university is a time for gaining in independence and confidence as well as getting a degree. So you have to ask yourself which do you want the option where you can go home as often as you like or the one where it is still viable to go home but not too often.
Also in terms of the course it is really important to go where you feel most comfortable with the course (or at least I thinks so). From your original post it seems like that you were more taken by Hull in terms of the course than Aston, (but I could be reading this wrong). Also if you are interested in Clinical Hull is the only uni in the country that gives people from its undergrad course a chance to apply to its Clinical programme in 2nd year. So that may be worth considering.
As you may or may not have guessed i'm slightly biased I'm at Hull and love it, but it's not for everyone else we'd've taken over the world by now. LOL
Hope this helps in some way

p.s. If you want any info on Hull 1st year just ask I'll be happy to give it you
