You have amazing choices! If you think you would be happy at Princeton go for it! But, if you think you would happier on the west coast with your UCs then go for that. I think you will get an amazing education at any of these schools, they are all challenging and all have good reps. Personally, UCLA would be my go to because it is extremely competitive yet also on the west coast where I think life is calmer there and it doesn’t get too cold. But this is not my decision.
Maybe make a pro and con list? I know so ordinary to do but could definitely focus on what you’re looking for. List things that you would like in a school and hopefully it will direct you to your school 
hope this helps.
