The Nucks one is the best, if a bit oversized. Generally I'm not a fan of the conformity, but they look kinda sharp. All the animations are just trying to make up for lack of style with fancy moving images
The Flyers one is pretty cool. I'd like it more if the logo was black not silver.
Our Leaf one isn't too shabby however
the Flyers spinning logo one is only cool because a Leafs fan made it for them
The Ottawa avatar is very classy. Leafs is great as usual. I've seen two Habs avatars: one average and the other (the one sported by perez) is just awful. It's too fast and has writing that is in blue red and white that is unreadable on the background.
