professionally in my side job as an artist and so I've done some actual research into what makes a great logo. It really boils down to three things:
1) Distinctive 2) Memorable 3) Instantly Recognizable
The Stretch Y is all three of those. It's also Simple, versatile, useable in any size, timeless
Sailor Coug does well here too, but falls somewhat shorter on some of these dimensions.
I love our logo.
