I'm trying to decide between USC, UO, Occidental, and CU Boulder. Any suggestions?

What do you care about? Environment? Prestige/academics? I would go to USC, even though it's in the ghetto it's pretty safe and has a good reputation and location (so cal). Plus it's ranked much higher nationally than any of the other schools you selected. So socially and academically it's a better choice, like I said it just depends if you like the campus (I'm uming you do bc it's on your list).
