I would say New York was the best city throughout most of the 20th Century. I mean, look how many great fights occurred at Madison Square Garden and Yankee Stadium. But since the 70's, Las Vegas has overtaken New York. Recently, New York has been making a comeback, mainly due to Trinidad and Cotto fighting there and packing the house. Atlantic City was doing well in the 80's and 90's and still does well, but for a time it was number two behind Vegas. It seems like its "grand" days are past.
