Symmetry is aesthetically more pleasing: the bandanna on the left balances out the GB logo on the left. Both sides now mirror the other, especially when you consider the two snakes and the way the text is arranged! IT'S SCIENCE!
But the bandana and the logo aren't symmetrical. Fuck science. If it's telling me I'm wrong, fuck science! I love the asymmetry!
I agree, I love the asymmetrical one!
