The Camarillo outlet is very hit or miss for me, although I guess all outlets are like that. There's not a huge collection of signature pieces, although there's a bunch of other stuff. Now is a good time to go, since the stores (or at least mine in Santa Barbara) are switching out their merchandise today. Avoid Camarillo on the weekend/ in the afternoon, it's hard enough to find parking, let alone purses.
I haven't been to Cabazon in a long time, but I'm pretty confident that Camarillo is the superior outlet mall. Plus, it's closer to LA and not so hot. Good luck!
