Edit:
@WanderingProtagonist is right in all the stuff he said based on a quick read of his post above, but that applies mostly to the bigger cities. Not sure which he's in, but yeah.
Fast answer for now (I can be back later with more, because I have been there a lot):
If you wanted to actually live there it's pretty iffy, but I enjoyed travelling there a lot, not only in the vastly more palatable 80s and early 90s, but also in the early-mid 2000ish era.
I was in Los Angeles quite a bit as a boy in the 1980s but obviously those days are long gone, but it was cool at the time, but all the girls I know from there who are still down there HATE it now. Even the ones who married rich/affluent men and live in comparatively nicer areas than I've ever been able to afford living in myself hate it, LOL.
If you like rural little towns on the coast, it can be cool in some spots, but personally I'd only want to travel there as a nomad. (If I wasn't into boats so much, I'd be some kind of RV nomad I suspect.)
I'm honestly not sure where I'd go for as the best place if I was forced to stay in the USSA, but since I'm so into boats all-in at this point I supposed it'd just be marinas up and down the Left Coast, and there are many interesting ones up and down Californian coastlines, but almost everything there is more of a PIA and more expensive.
Compared with South East Asia though (especially Vietnam that I like the best) and Thailand, damn, it's pretty dismal in comparison!
But if for some reason I had to live in California alone and couldn't go elsewhere, I wouldn't complain:
Various small coastal towns, the Redwoods (back when they weren't up in f-ing flames from wildfires), Mt Shasta (watch out for UFOs), are all pretty cool if you're into out of the way places, I suppose.
But yeah, like he said, if you're not loaded with $$$ to be in the nicer areas, it's really not a great place unless you really find your niche.
If I was forced to say on the Left Coast for life, I'd suppose I'd sail up and down the coast in the small rural coastal towns enjoying the rather dismal American gothic mystique, white and Latina women (who tend to be bored out of their minds by the local men), drinking beer, and just appreciating the natural scenery. I'd go Washington or Oregon over California in most places myself, but to each their own.
Everything is better in so many places abroad though! Happier Abroad is no joke!
