UCSB vs. UCSD: STEM

Hey everyone,
I have been admitted into UCSB and UCSD and have been indecisive about which to attend. They will cost about the same so price is not a factor in this. I have visited UCSD but not UCSB and unfortunately I will not be able to due to the corona virus. I will be majoring in data science.

How is each school in STEM? How is the opportunity at each school? How hard/easy is it to find and obtain research and internships at each school?
