OK I've never been in control of a real life B767, however I do enjoy Flight Sim and hey if both tech crew were incapacitated and there were no other qualified pilots on board then I wouldn't hesitate in using my (yes totally unqualified but better than nothing at all) Sim experience(?) to try and land the aircraft safely.
I sure as hell wouldn't even try and compare myself to a professional pilot, and frankly I'd be happy if I got the bird down with fuselage intact and without loss of life.
My two cents (or pence, depending on where you're from).
