Haven't traveled nearly as much as some in the thread but...

Liked: SFO, except United sucks badly.
Denver...have only been there for a few layovers but very nice airport.
Vancouver...have travelled there for over 20 years, maybe I like it because it has got so much better over the years, but very much reflects the city. Also like the easy transit connection downtown.

Good and bad:
Halifax: Love the airport, it's a great model for new/remodeling mid sized airports like Edmonton and Saskatoon. Way, way too far out of the city though. Would that be because Shearwater is right at the harbour?
Saskatoon: Thanks to BigTime for the shoutout to YXE. I really like that airport, go through there at least once a year, but am really looking forward to their renos. They did their last expansion right before 9/11, so really no amenities on the other side of security.
Pearson: As stated above, depends on the terminal.
Dorval: Old, cramped but AC had tons of hot French women working there who were surprisingly very nice.
YYC: Meh...but that might just be because of familiarity.

Don't go there:
Oakland: I swear the gate next to us when we deplaned was going to somewhere in Mexico and there were livestock going on board, and that scene didn't look out of place in that crap hole.
