I like the red one the best. It really shows their color. ;D
“I am a Pro” 
I know a few people who would appreciate that. 
The red one is pretty cool, though, I would prefer it without the logo…
Don’t really like any of them, but the lessor of them would be “I am a Pro” though that sounds pretentious ;D
