Pre-Med at UC Schools?

So I’m deciding on going the pre-med route and am wondering if top UCs like Berkeley and UCLA will make it extremely difficult to get a good gpa. Is it worth it to go to UCSD or UCI to avoid gpa deflation? Are they even any easier than Berkeley/UCLA? I like the prestige of top tier schools but is it worth anything? I’ve toured all the schools and I like their campuses on an even enough level to choose any. Thanks
