Since you are wanting a home defense weapon and/or carry weapon, you want reliability. For a reliable and relatively simple 1911, I say stay away from any 1911 with a full-length guiderod, firing pin safeties, bull barrels, or external extractors. I have some models which incorporate one or more of the previous items and won't be getting another including any of them.
I had a Taurus PT1911 I traded because it was just a poorly finished arm, both in build quality and actual finish. Their customer service wasn't too helpful either.
I have a SW1911 which the firing pin safety got buggered up and I noticed light strikes, luckily, at the range. I fixed the problem and don't doubt that weapon's reliability. I would still recommend the S&W because their customer service and repair are very accommodating and swift.
Another thing is 1911s can be picky about what ammo they like and also about which magazines they like.
Sure, there are a lot of 1911s that work all the time. However, be prepared to invest a little in "experimenting" with loads and mags. Keep in mind they were originally designed to feed round-nose bullets. Also, test out the gun after a field strip and re-lube. There is a tendency to replace a bunch of parts just for the sake of it or the "tacticool" factor and not all of those items are exactly drop-in. You want to make sure the pistol is reliable before making any changes as a baseline. If you do change something, make sure you do one item at a time just in case a problem pops up you can isolate if the change caused the problem or not.
I love 1911s for their elegance and simplicity. Detail stripping is a snap. The 1911 is very concealable. It's like a Honda, parts are everywhere and easy to find. Ammo is widely available and in numerous loadings.
