Look both of these logos have annoying hockey sticks in them! No, but it's cool. I'm giving the Penguins this point for not writing out the entire team name within the logo. It also wouldn't hurt if the Islanders logo lost that puck. People mocked the fisherman guy, but that was actually a clever logo from back in the '90s.
Islanders are people and people are the dominant predator on the planet. They don't Penguins but that doesn't make the little guys safe.
I'm a fan of the outline of Long Island in the background of the Islanders logo, but I've recently been informed of the deep ties that elements of the Penguiins logo have to the city of Pittsburgh. Despite the fact that it's not easily recognizable to anyone not from Pittsburgh, I think it's more important that the logo means something to the home town crowd. And apparently it does.
