Best University of California for me?

I'm a senior and I have to apply soon so I keep wondering what UC fits me the best. I see very good qualities at the UCs I've been looking at, but there's always something that I don't seem to like, it's probably me being nit-picky, so I would just like to have other people's opinions. :) I really want to attend a beautiful UC, I'm a very nature-loving person in general, so I love having lots of plants around, but I also don't mind some good architecture. :D Next, I'm not a big party-er, I'm not into drinking or getting high or anything, so social life of a campus is a so-so quality to me. I love participating in school traditions though! I'm big on the school spirit thing. Last...I'm a pretty good student I think. I got into the ELC at my school, so I have some guaranteed admissions already, but I'm still trying to keep an open mind. Thank you for any opinions!
