There's a lot to like about many areas of California. Which ones may depend on your weather, cultural, etc. preferences. But Silicon Valley proper I find not particularly appealing; housing costs are only part of the reason. (SF itself has well-documented pluses and minuses.) I don't live or work in CA/SV. But if I were in SV but no longer needed to commute, I might well stay in CA but I'd probably move somewhere out…
I think SVs appeal is that you can leave in a quiet suburb close to a lot of easily accessible nature, while still having Amazon 2-day shipping, ridesharing, Uber Eats, and luxury retail. There's not many places in the US like this. Europe has a lot but there's not much tech jobs in them. You are also close to SF if you like the madness of the city every once in a while. Other suburby places with nature easily access…
People I know dislike the fact that most of SV is a typical suburb indistinguishable from what you see in any random Florida city. And consider how many busses bring workers from their apartments in SF down to the office in the burbs.
