Justice at SMO is good. Beach Cities Aviation at Hawthorne good. They even have a Corvallis 400 you can get into, if you like. If you need a good going through, ask for a BFR with DPE Pat Carey at BCAA.
Long Beach is busy and tower can be a bit anal, but it's good high density practice. Torrance is a nice field and quite near. Compton is a bit ghetto, but there are some interesting aircraft there. Fullerton a well run field. John Wayne even busier than Long Beach in case you crave the rush of mingling with big jets. Just watch out for the permanent TFR above Disneyland/Anaheim that goes up to 3000ft. It's easy to bust.
And if you're ever out a bit more East and have a twin rating, you're welcome to borrow the old Commander with a quick checkout.
