basically there are two which i can't choose between.
The first has a great atmosphere, loads of places to go out, lots of places to eat, always has loads of events, and is a gorgeous place to live. There are also loads of unique shops and restaurants as well as chain ones. But the course i want to do (psychology) is pretty new there and doesn't have a brilliant rep yet, and doesn't seem to cover all the modules i'm interested in. It isn't accredited by the british psychological society yet either as it's so new. Also, the accommodation isn't as nice, even though it does have amazing views.
The second place, while it does have a good atmosphere and loads to do, it's very close to home and so it's somewhere i've been to loads and i guess the idea of going there isn't as exciting. I guess the nightlife and social side doesn't appeal to me quite as much. The uni is lovely and everything, and so is the accommodation as it's all been done out. The degree scheme has a lot more going for it too, as it's actually accredited and there's a lot of world class research that's been done there.
TL;DR: As stupid a question as it is, would you rather go to a uni that's more reputable but not as much of an "adventure" (literally 20 minute drive from my house now), or a uni that doesn't have as much going for it in terms of the course (yet, remember it is new) but has much more to offer you in nearly every other aspect?
The second one sounds like the best option.
What are the two choices by the way? Just had a look at your UCAS, if its a choice between Cardiff and Aber/Swansea, I'd go for Cardiff
I'd go for the accredited one, purely on the basis that the degree you come out with will be worth something.
But for another course (ie. where accreditation isn't an issue) I would go for the one with the adventure attached.
Personally, as a fellow psychology applicant, I really would recommend going with an accredited course where possible. University is as much of an adventure as you make it, so I'm sure you can ensure that you have a good time making friends and that sort of thing- you can sort of make up for it. But you can't make up for a course that is (currently) below par.
At the end of the day, you're going to university to get a degree (well, I assume that's your main motivation). Of course it's important to have a good time, but in twenty or thirty years you don't want to be regretting your degree choice.
