UC berkeley Econ vs. UCI Business Admin

Hi! So i was a UC berkeley student back in 2016 as a premed student but withdrew fall 2017. During the time of withdrawal, I took some classes in my local CC and decided on going for the Business Admin route, I even have an AA degree now. I tried applying to schools and got into UCI’s business program. I wanted to ask your opinion, should I accept UCI or go back to UC Berkeley regardless (i can still be readmitted back if I choose to). I am just confused because I am stuck in this mindset of lost opportunity of getting a degree from Berkeley but I want to take and learn about Business admin for sure. If i go back to berkeley, i can still try for Haas but there is no guarantee I would get in and would then be forced to take Econ as a major. I would really like to hear your opinions on this.
