Both UCLA and Cal are great choices. You can’t go wrong with either.
At the end of the day, it’s really where you think you “fit” in terms of the academic environment and the overall location (San Francisco vs. Los Angeles). Also, don’t weigh the Chancellor’s Reception or Bruin Day strongly as a factor into deciding. Visit on a regular day if you can.
If you live close to one, it’s okay to step out of your comfort zone and go to college a little bit away. New experiences are great!
And just because I’m bias…
Berkeley is on semester system 
I can’t tell you how much of a pro that is (no one wants to take finals three times a year). And yes - you can take so many classes on a semester system also, you’re not limiting yourself. But I hear quarter system is cool too, lol.
