Leeds or Sussex?

Hi everyone,

As you can probably tell, I'm completely torn between the two. I have offers for both (AAB) and I'm hoping to study neuroscience.

Now, obviously it's extremely important that the chosen uni is good for my particular course, however I have no doubt that both are excellent unis for teaching quality so this does not overly concern me.

My dilemma is more that I don't know which of these cities would suit me better. I've heard all sorts about both - Leeds is wonderful, huge and exciting, full of things to do with a great student area. Conversely, I've heard it is grubby, dodgy and just TOO big and impersonal.
Some say Sussex is aesthetically beautiful, great community feel, just enough shops etc in city centre to be what you need. Then others say it is small, boring, poor nightlife, poor sports facilities and the uni itself is experiencing a lot of problems.

Anyone who knows anything about these unis and their respective cities, please shed some light on this and make my decision a little easier.
