The uniforms and colors are kind of a draw, although the Eagles have the better logo.
Cuisine isn't really a strength for either city. They each have their signature food, and Kansas City barbecue beats Philly cheesesteaks & hoagies, which I thought were a little overrated. And I've never been to KC, so it's likely I haven't even had authentic KC bbq.
Hollywood: Don Cheadle, Chris Cooper, Ed Asner, Dennis Hopper and director Robert Altman are/were from Kansas City, which I didn't know. From Philadelphia, we have Will Smith, Richard Gere, Kevin Bacon, and director Sidney Lumet. Kind of a draw, so far. Philly has a deeper bench here, though: Kevin Hart. Kat Dennings. Bradley Cooper. Robert Picardo from Voyager
. Kim Delaney from NYPD Blue.
Seth Green from Buffy the Vampire Slayer
. Molly Ephraim, who was almost too adorable as Maybelle in last year's A League of Their Own
. I give this one to Philly, but it's not a wipeout.
Music is where the two cities really hit each other hard: Kansas City was a hub of jazz from the '20s-'40s. The Count Basie Orchestra was from Kansas City, and I think that's where bebop started. (Charlie Parker was originally from Kansas City, but I think he didn't really break out until he went to New York. If KC wants to claim him, I won't argue, I just don't know if they do.) If I had a time machine, Kansas City in the '30s might be on my itinerary. It might still be a good place for jazz today, for all I know. But Philly was more important in the '80s, and nearer & dearer to my heart. Hall & Oates; Patti LaBelle; Jazzy Jeff & The Fresh Prince; Sister Sledge. To name but a few. Philly also has a wider spread of things to choose from. I mean, really, pick your American music era and Philadelphia is right in the middle of it. Billie Holiday. Chubby Checker. Stan Getz. The Roots. Pink. The Dead Milkmen, if you're into punk. Frankie Avalon, Bobby Rydell and Fabian were all from the same Philly neighborhood (Lower Moyamensing, about which I know nothing, but I'm just gonna go ahead and guess it's got a lot of Italians?
) Joan Jett and Taylor Swift are originally from Philadelphia(-ish), but they didn't break out until they went to L.A. and Nashville, respectively, when they were still teenagers, so I don't know if Philadelphians claim them or not. I don't think she was ever huge, but there was a singer named Res I was into about 20 years ago, who's from Philly. I haven't kept up with her, but I do still listen to her album from back then, once in a while.
So I'm going with Philadelphia, mainly on the strength of the music.
