I'm going to break the mold a bit - I LOVE both NYC and LA!
Westwood is really beautiful... a college-town feel but with lovely stores and restaurants, palm trees everywhere... of course sunshine. Tree-covered streets full of lovely houses give it a very neighborhood-esque atmosphere. You don't feel like you're in a big city in the bad ways, but of course you still have all the conveniences of a large metropolis.
I've found UCLA's part of LA to be really... perfect. Beautiful Santa Monica is only a short drive away... oh instead of carrying on rambling, here are some pictures I've taken of Westwood/the law school/Santa Monica/PCH. Ignore my stupid captions.
