The obvious answer here is the Avalanche. This logo has great colors and a classic design that I don't think will ever go out of style. The Oilers on the other hand — stop spelling out the name of the team in logos!
I don't know what Oilers are doing in snow-capped mountains, but they would certainly be crushed by an Avalanche.
Both teams are aptly named and have respectable color schemes. However, as far as having a logo that symbolizes your team. There's almost none better than the Avalanche. The Oilers logo has a simple copper drop and the name of the team. The Avalanche logo incorporates an "A" as a mountain down which an avalanche is falling. How do you improve on something like that? The Avs complete the easy sweep.
