If your goal is UCLA or UCB, then you should enroll in an Honors program. Do you have a 3.5+ GPA from your high school? (If not, you can get into Honors later based on your college GPA.)
Both De Anza and Foothill are good. (And they comprise one community college district, so it’s relatively easy to mix classes from both, over the time you’re there, if you want to.) De Anza is bigger overall, but it appears that the Honors course offerings at Foothill may be more extensive. (And the Foothill Honors website seems to be more up-to-date.)

Are these the closest CC’s to your home? West Valley is also good (and also has an Honors program).

It also depends on your extracurricular interests, as the different campuses have different strengths. This can end up outweighing minor differences in the academics.
