The Habs fan base can certainly be sensitive and annoying at times, but there are teams I dislike significantly more in the league(Boston, NYI, Edmonton).
There hasn't been a true on-ice rivalry between the two teams in my lifetime(I'm 26) and I don't anticipate there will be one anytime soon with the Atlantic going back to normal in October. Edmonton and NYI fans annoy me to no end, Boston was a legitimate rival who kicked our ass in the playoffs 3 times in a decade. When I was a kid, I hated Ottawa and Philly, but those feelings have faded as well over the years.
Vegas is just a team I thoroughly enjoy watching, and I do believe they're the second best team in the league (Tampa being #1)
