Assuming you have received an identical offer for both, which would you choose as your firm?
To take into account:
Reading has better transport links home.
Kent is higher on league tables, but Reading higher for subject.
Kent took longer to respond (about 2 month) than Reading, less interested and more likely to reject if you're down a grade?
Also don't know the area very well but good pubs, clubs, bars, restaurants and shops would be good.
