I own Springfield G.I. and an XD-40 5". I like them both equally, but do find myself shooting the XD more than the 1911, maybe it is still new? I like the XD, trigger is on par with other striker fired pistols to me, no different than the Glock I had. 1200 rnds, 1 FTF, which was due to the 12 rnd mag being tight and it was the first magazine I ran through the pistol. Since, zero failures of any kind, zero rust, or any other problems for that matter. I have had it wet, muddy, rained on, left in a glove box, in and out of air conditioned vehicle into very hot humid weather and no rust or any other finish issues thus far. I do keep a light coat of RIG grease it on after I clean it(RIG dries and does not leave it greasy by the way).
I think the guide rod problems are with the 3 and 4" models since they have a captive guide rod system, versus the 5" uses non captive, very similar to a Ruger semi auto. It has fed any ammo I have tried to put through it. I love the pistol and highly recommend it, also get a Houge slip on grip for it, does wonders for them in my opinion.
All of this could be said for my 1911 as well, I love my 1911 and will never not buy them. But, the XD is a fine pistol and would/will purchase more of them.
ETA: As far as comfort goes, the XD and SA 1911 are one in the same to me. Which is why I bought the XD, it felt very much like the 1911 but is lightweight, light rail, high cap/doublestack mags.
