UCLA or Berkeley? Econ/Stats

So I already committed to UCLA but the waitlist just came out today and I got into Berkeley… I current major is undeclared in both schools but I planned to major in economics or statistics (or something related to business). I know Berkeley has a better business program but I heard it’s a lot pressure. I know studying engineering is really stressful in Berkeley but I don’t know about business…

I’m okay with pressure but I’m not that smart and I don’t want to be too stressful in college everyday…Can someone (especially if you study business-related area) give me suggestion?
