Well, your disdain for the 1911/2011 platform is pretty well known, so I don't think we can take that comparison objectively. It's a mystery to me why you choose this forum given your preferences, but to each their own.
I'm going to need some help understanding "better in every category". Better how? Better why? It's not a Master Shop gun, so It isnt in the materials. It isnt in the finish. It isnt in the assembly. It isnt in the fitting. if you mean shooting, measured how? best I can tell from your posts you dont shoot often or use a shot timer, so are we going by feel? Some accuracy standard? How did you measure the performance of each?
If you just like it better, then great. Im glad youre happy with it and I hope these US X5's turn out to be as good as their german counter parts, because those are phenomenal.
But until I see a coin and an assessment of the fit and finish (especially firing pins, locking lugs, frames, and slide to frame fit) after 15-20k rounds, you can keep it, because I dont think Sig has changed one bit for the better over the last decade. And I hope to be proven wrong, because Id love for Sig to be back to making good *, not just a bunch of *.
