I was gonna say NYC has the most in terms of raw numbers, and it isn't really close. It certainly has the most art deco towers. But I actually think LA might have more art deco buildings overall if you consider all those small scale commercial buildings scattered all over the place. You don't really see art deco at that scale in NYC. There are entire retail corridors in LA lined with one and two story art deco storefronts. Thousands of them. Fairfax, Melrose, LaBrea etc are all full of art deco if you look closely.
