Well, plus..you've got an offer in the hottest market in your field, and a positive job offer. Looks good on a resume, as I always say..
The minus side is, like most specialized fields, the hottest markets have the fiercest competition..so who knows..it's your life..if I was younger, I'd say go for the experience, and see what comes up in the end..you can always tell 'em you worked in LA..good luck.

I wish I'd said that.. The Staircase Wit
