The Colt XSE is nicely slim, for a better fit in my hands, and it has the junction of the trigger guard and front strap nicely sculpted to allow the weapon to ride lower in my hands. This little feature makes ALL the difference my hands; 1911 pistols without a high-cut front strap, or undercut trigger guard, now feel strange to me.
FWIW, I have large hands, but my fingers and thumbs are medium to small.
I have had good luck with full-sized 1911 Colts, over time, so my poll choice comes with this recommendation for a full-sized weapon. It is just as easy to conceal and draw a Govt Model as a Commander, realistically. Been there, done that.
