I've been shooting for 30+ years, much of it competitively. Over that time, I've owned more than 100 firearms. Presently, I own five Glocks, seven SIGs, Beretta, Kimber, Kahr, S&W, and a few others. The P229 Elite in .40 S&W is the finest firearm I've ever owned. Period.
The trigger is glorious, the SRT is nice (personally, I think the regular SIG reset is good; the SRT is just icing on the cake), and the beavertail in combination with the SRT makes for a fantastic rapid-fire experience. None of my SIG triggers are "stiff", including my 1986-vintage P226. Like all SIGs, they like to be kept lubricated. They're not quite as smooth as butter, but they're close. By comparison, a Glock trigger feels like it has sand in the vasoline, if you know what I mean.
