Which fits your hand the best? Not my hand, your hand. On which can YOU most easily access the controls (SS, mag release, etc)? Which feels best when you shoot it?
At $$$, both of these are fine pistols. reliability of both is excellent, so buy what works. You won't care ot oh-dark-thirty when you reach for it whether it is a Springfield or a Glock, just that you know you can hit your target.
