I really enjoyed Destiny's Diaries, Vargas, and how Claremont handled Gambit in the beginning of X-Treme. I also really liked the Fury storyline, Savage Land stuff, and End of Greys. But as all of those runs carried on, he lost me. The Hellfire Club stuff was so convoluted, God Loves, Man Kills 2 was real bad, and the rest was just pretty meh.
Revolution was bad tip to tail imo, and I loved the idea of Gambit and Rogue leading their own teams. The stories just didn't work for me though. I preferred the Scott Lobdell issues between Claremont and Morrison to all of Revolution.
