Each UC has its own qualities and vices. Berkeley has a good reputation but rents are atrocious and its in the middle of a smallish city and I find it dirty, personally, but it is right across the bay from SF if you're into that scene. Berkeley actually truly shines in its graduate program, and its undergrad program is not quite on par with its excellent reputation. UCSB has some great parties on the Streets of Isla Vista, but it is affectionately known as HIV, due to the uncleanliness of the populace 😉 . UCSD i hear is nice but antisocial, no personal experience there. UCSC is full of weed-smokers and is not for the academic minded individual, as it seems to be the easiest UC to get into, and i believe that you can go there and not get a GPA (old rule?) I myself am a Davis man, a bit biased, i know. Davis is nice, fairly small, flat, easy to bike around... HOT AS HELL in the summer and cold in the winter, and not as many cows as you might think- only 1 barn full of em on one side of campus and you can only smell em at night when the wind blows the right direction.. 🙂. UC Irvine/Riverside; lots of asians....? To each his own.
