Comfort: This isn't even a contest. While apparently not a single person working at Converse has thought to add arch support after 80 years, the PF Flyers Center was one of the early pioneers of arch support and the system (PFFlyers ACTION WEDGE) is still awesome and only gets better as you wear the shoes down into thick canvas socks.
Durability: About four years ago they would have basically been tied, but after Nike bought the Converse name a few years ago corners were cut and the biggest one was switching from double ply to single ply canvas on the entire mainline (some of the special seasonal and designer Chucks still use double ply). New Chucks don't last as long and don't wear in quite as well as old Chucks or any Center with double ply canvas. Center wins it again.

Detailing: This is a real toss up. I prefer the Center's silhouette but I find the toecap on Chuck's sleeker. I also think PFF needs to tone down the racing stripe on the back on certain colorways. I can't really pick a winner here but I prefer the PFF.
