Points naturally, doesn't have a mushy trigger like the Glocks, S&W's or XD's, and SAO unlike the Sig's SA/DA nonsense. Feeds semi-wadcutters (Glocks won't)... the guns you mention all have a capacity advantage on old slabsides, but IMO it ends there. Glock's reliability has sure taken a kick in the crotch since Gen 3's...
I've owned Glocks and Sigs. I like the XD of the bunch, but the M&P is just another Glock. Still carry a 5" 1911.
To each his own.
