SoCal wins by a huge margin.
There’s simply too much here. Lots of culture, different scenery to look at, lots of history. An incredible amount of people. Always something going on.
Although NorCal (Bay Area only) is really amazing and scenic in terms of landscape. Especially parts of SF, Oakland, Berkeley, Marin, etc.
But other than that it’s relatively empty and soulless. Especially SF, it’s filled with tourists and inaccessible to anyone else. But even in Downtown Oakland it’s dead, rundown, and a relic of a bygone era.
