The Islanders are their fan base are a bunch of morons. Right up their with Oilers and Sens fans. It is probably why no one gives a f*** about the Islanders and what they do.
The Rangers and their fans are cool. Lot of respect for that organization.
Hope that helps.
In terms of play, the Islanders play hard and work for their chances. Don't give up on the forecheck. Defence is a little more leaky than I remember. Rangers seem to play more of a free flowing style.
Fan wise.... I hate to get into a pissing match. But I've never seen an angrier bunch. Bruins are up there for that too. They really seem to have a "You gave my dog side eye, now I'm going to sucker punch you and dance over you while you're down" mentality. Just really angry.
Even their Athletic writer wrote a piece about the Tavares booing and shit on the Toronto market while also throwing in an Ohtani shot at the end.
You wouldn't really see that in a Toronto piece, as they'd either be praising something that isn't there or for the most part, heavily criticizing their own market. Aka good or bad, it's about us, not some "ha ha ha losers" piece about another market we frankly don't care about.
