Round or Square?

Ok, after a few small, recent successes with the DO on our scout camping trips, I'm thinking about buying a waffle iron. Was looking online and saw the griswold #8 round and thought that was pretty cool, then I saw a square #11, which also looked pretty neat. I'd like to buy a nice old one, just 'cause they look cool. Any tips or hints on buying a vintage one? Round or square? Will one shape taste better???
