I think you summed it up quite nicely. All factors considered, the PX4 is simply one of the "best" guns you can buy right now. I'm very happy with mine. Not a bobble in about 1400 rounds.
That said, I still love the 92. On paper, the PX4 wins. But there's intangibles in terms of shooting/handling that still keep the 92 very relevant for me.
