There are definitely things not to like in SoCal (but arguably that can be said about almost anywhere), and completely understand why a lot of people wouldn't want to live here, but there are also things to like about it as well.
I've lived in the Northeast, Southeast, and SoCal, and I can say it's definitely nice not having to deal with winter weather, gnats in the summer, crazy humidity, and crazy hot days on the regular, to name some things. Also really nice to carve up some of the canyon roads and get some really amazing views in the process, or cruise the PCH (when it's not busy, of course).
