I’d actually suggest if anything, that is understating the picture for aspiring undergrads. That is essentially a research ranking, which of course is one possible criterion a possible undergrad could use, but not at all a necessary one, and not the only one.
So here, for example, is a different US News ranking, the top 70 (with ties) undergrad programs at National Universities that scored particularly well in a peer survey about dedication to undergraduate teaching:
https://www.usnews.com/best-colleges/rankings/national-universities/undergraduate-teaching?_sort=rank&_sortDirection=asc
Some additional names off that list (so eliminating overlaps):
Santa Clara (t-17)
Biola (t-31)
Loyola Marymount (t-31)
Pepperdine (t-45)
UC Santa Cruz (t-45)
University of San Diego (t-56)
UC Riverside (t-70)
But wait, there are more! US News also ranks LACs for undergrad teaching:
https://www.usnews.com/best-colleges/rankings/national-liberal-arts-colleges/undergraduate-teaching?_sort=rank&_sortDirection=asc
This includes:
Pomona (t-7)
CMC (t-30)
Pitzer (t-35)
Harvey Mudd (t-42)
Occidential (t-42)
Scripps (t-61)
But wait–there are even more!
US News also ranks the top engineering programs where there is not a PhD program:
In the top 50 alone (there are more), this adds (so again eliminating dupes from above):
Cal Poly Slo (t-8)
Cal Poly Pomona (t-10)
San Jose State (t-15)
CSU Long Beach (t-23)
CSU LA (t-30)
CSU Fullerton (t-37)
CSU Sacremento (t-37)
CSU Northride (t-44)
CSU Fresno (t-44)
And so on. Lots of different ways to think about what might be the best sort of college for any given individual, but basically California is loaded with great options in every major category. And many of them are publics, both UCs and CSUs and indeed others I didn’t even get too.
So yes, it is a great state for colleges.
