If you cant decide between the courses then try and visit both campuses and see what you like the look of. Its another major factor in enjoying your time at university. Brunel has a good campus, although I do prefer UKC where I did study before. Ive never been to Leicester so cant help you out with it.
I visited some I was close to choosing until I actually saw the campus, and was put right off ever wanting to stay there. I got a very good offer from Brighton until I visited the university and immediately rejected it.
