The 80's had two of the greatest professional sports dynaties of all time. There's something to be said for something being "dated". As such, I like the Islanders and Oilers sweaters.
Everyone knows that and instantly thinks of Gretzky when they see the Oilers' logo, but I don't think that makes it nice. If they had a nicer logo during the 80s, that logo would be equally as historic, but it will also make it nicer today.
The O6 logos are nice, not only because of the history behind them, but also because they never get old.
