The Hurricanes logo has been unbeatable to this point in the tournament. It's a strong logo that's simple and sharp. The Senators logo gets a bit bogged down in detail and probably won't even be in existence much longer.
Mother Nature tends to leave a path of destruction in her wake when a Hurricane is involved. Even Senators aren't safe.
Neither logo makes an effort at representing their home city. The Hurricanes name, though, at least gives you a hint to the geographical region. Plus, I'm a big fan of the puck used as the eye of the storm. Chalk up another sweep for the 'Canes.
