The problem I see is that nothing John said was that one is better than the other. Just that both have their reasons to have been used at different times. Claiming one is better than the other due to specific situations doesn't negate that overall both designs are perfectly valid.
And some unsolicited advice: There is a way to make your point and engage in a discussion, even if you disagree. But when you resort to back handed comments disparaging the other your credibility takes a nose dive. I am sure KeepCalm knows a great deal about the platform, and I >know< he knows more than I do. But for many of us, we have sat with John and discussed the 1911, watched him diagnose problems, watch him work magic on small machines that we could never have guessed. So go into any "argument" with him based on the fact that many of us reading his comments know him, know his capabilities, and know is expertise. Attacking it isn't going to come across well, regardless of how righteous you believe you are.
It took me a long time to learn this, and I alienated many a folks in the past due to my inability to accept that something I know isn't exactly so all the time.
