Stop drawing comparisons. You're you, and he's him. Period. Music is not a competitive pastime (unless you believe what you see on TV) - it's a form of expression.
Back out gracefully. Alternate opening slots. If he wants to consider himself the faster guitarist, let him. Personally, I couldn't care less about speed or flash. I'm interested in what the guitarist has to say with his instrument.
