I'm from the Philly area. I can't speak to Tyler's program in great detail but Philly has a pretty decent art scene - lots of artist run spaces and regular openings of small shows where lots of artists go to hang out (second Thursdays, first Fridays, etc.), and a few bigger established places as well. Lots of artists are connected to NYC as well. Having never lived on the west coast I figure there could be some differences in schools of thought that could be fun to explore in grad school.
