Since they both thrive in California, I maintain that you should go with the superior-tasting fruit, which is fig. Loquats are pleasant, but that's about all I can say for them. Figs can be knock-your-socks-off great, a top-tier fruit (if you like them, of course). I can't grow figs in the ground, due to RKN, but yeah, I should try in pots.
