I haven't gotten into the collector mindset when it comes to firearms, so my choice is based on what is the simplest to maintain, something that I don't need a gunsmith to tweak or even fix, reliable when its called for and remains reliable past the point of thousands of rounds being expelled through it.
Whenever I get a chance to shot a weapon that is not my weapon of choice, I tend to fall in love with its ability to fire a round down range. Once it misfires because it gets a little dirty, reacting to a scenario causes me to forget to operate the safety that's where my love affair ends.
My buddy and I take his P226 and my G17 out to the range all of the time. I even considered buying a Sig, until I consider the aforementioned criteria. It's like the difference between a Chevy and a Ford, no one is better, just a matter of choice.
