I've recently learned that I'm a very indecisive person when it comes to choosing a college.?

So, I was wondering if someone out there would help me out. I'm not asking anyone to tell me where to go I just want information about the schools so that I can make a choice. I don't exactly know what the schools are like so any info would be helpful. The colleges I'm debating between are UC Irvine, UC San Diego, and UC Santa Barbara. THANKS!!!
