Two others that I've seen which weren't on your list (you may not have seen them):
- Meet Joe Black: not one of his better efforts. Anthony Hopkins give a much better performance.
- A River Runs Through It: I didn't much care for the film or his performance
now I saw your worst-list. ok, fine. only one: the Cyborg :) this shit-movie is in classic-style, so... yes, you're right, but, it's a classic like Mona Lisa :)
Seven, Fight Club, TAOJJ, Inglorious Basterds, Snatch, 12 Monkeys, and Burn After Reading are all stellar examples of Brad Pitt's versatility. He's very talented as well as beautiful.

I haven't seen them yet! I've planed to, for a while, but as far as today, I've not seen them...
Troy and Benjamin Button: the worst movies of my life.
Well, 12 Monkeys I have to take a rewatch with, but I still will stand on my choice on Benjamin Button. Amazing movie :)
