Personally I feel that SJSU CS and SLO CS are probably on par with each other since they the most selective for that major.
CS is a very popular and selective major at both the UC’s and CSU’s. The Cal states also give preference to local in-service area students while the UC’s do not.
SDSU would probably be a notch below but there is a large tech sector in the San Diego area where internships/jobs are readily available. They are one of the most applied Cal states besides Cal State Long Beach which makes them more selective overall.
UCSC and UCD are also very similar with UCD being overall more selective. Proximity to the Bay Area and Silicon Valley make them good options for Internships and post Graduation jobs.
In general, if all the schools are ABET accredited for CS and CSE, they will have similar curriculums. What sets the different schools apart is more location and school fit/vibe.

As California residents, we are lucky with so many great schools within the state. Much will depend upon on where your student will be accepted and which schools work academically, socially and financially for her.
Having had 2 sons go through the process and graduating college, one at a Cal state and one at a UC, in the end they landed at the best school for them.
