UC Davis vs UC SC vs SLO CS major

My son got accepted at UC Davis, UC SC, and SLO. He is not able to make a decision between UC Davis and SLO. He could not visit either campus as we are out of state.
Any guidance, feedback or experience will be appreciated.

All colleges CS major

@sandycc, both schools offer a high quality education, so there really is no “bad” choice here. What are the primary considerations? Quality of the program? Costs? Climate/geography? Social life? Since you said you have not been able to visit either campus, I am assuming that climate/geography is at least part of the consideration. What activities does your son enjoy?

I have lived within an hour’s drive of UC Davis my whole life, and I have a son (English major/Ag. minor)who is a Junior at Cal Poly, with my daughter (Agricultural Business) set to start there this coming Fall. I will help with any specifics that I can.

Where did he end up going and why did he choose it?
