So far here are my impressions:
UCLA: Awesome campus, academic etc. Probably (definitely) my favorite so far. All the old architecture (Such as Royce) is awesome and I really liked the entire atmosphere. Plus it's not quite as crazy as Berkeley. I really like the environment: although I'm certainly not a surfer type, but it was quite diverse and I really liked its academics. The majors I'm interested in they are strong in. I really do enjoy it. As an added bonus my mom went there, so it would make her happy >.> (Although I"m leaving that out of my decision) UCLA seemed like a nice campus with a lot to do and great academics.
UCI: Really sort of strange. Upon arriving on campus it's no LA or Berkeley in grandeur, and the architecture was really new (reflective of how relatively new it is.) Our tour guide was not obnoxious (the one at UCLA was, and kept on saying that all these famous physicists won the Nobel PEACE Prize. Something doesn't click with somebody like the UCLA Student (who got admitted to Stanford) who is a PolySci Major, but yet so unaware as a junior...) Anyways.... I digress. UCI was pretty nice but suburban, and didn't seem as serious. Also due to the surrounding area there seemed to be less to do. On a side note, when I took dorm tours in Middle Earth (that's pretty awesome/cheesy lol) I saw a guy playing LoL. Pretty funny. Also super supersuper super asina. Even for me, and all my friends are asian >.> Mom didn't care for it, because the dorm tour person (a sort of awkward overweight, but incredibly friendly hispanic girl) said that at times it was loud at 3am. Mom was freaking out about studying etc etc etc, but I"M sure it's 90x better than most other campuses.
UCSD: Well, I've heard it's great academically (with regards to the sciences especially), and our tour guide ended up being a blonde. Just an anecdote. So we went around, the library was awesome. Super awesome lol. But in any case she went around, constantly saying all that there was to do. Considering what i"ve heard I"m somewhat skeptical, and I'm sure she was told to say it all the alleviate concerns. I think it's really ard to judge on that front. Also, in the introductory video the Chancellor in a monotone voice said "There are many Educational Opportunities at UCSD" Really passionate... UCSD sort of came off with a bitter taste, and the school sort of house sytem was weird. Can anybody from UCSD either defend or attack my points, and describe the school system better than the tourguide did >.>
If anybody goes to any of these schools, and has anything at all to say, that would be excellent
