Recommended Housing for Engineering Students?

Hello! I was recently admitted to Cal for EECS, and I received Regents as well. I’ve been looking at housing and have narrowed options down to Unit 1 and Foothill, though I’m not really leaning towards one or other. Does anyone have any suggestions? I’m still open to housing outside of these two. I was also wondering if Regents would help with getting your preferred housing? I read that it just guarantees housing and nothing more. Thank you!
