I only own one but I looked at number of them when shopping. The Kimber Custom II I never hit it off with; it was a nice gun in every respect but I felt it lacked a certain tool-like quality when I picked it up. It seemed designed more for fun than for serious business.
I thought the Springfield Loaded was going to be the hot ticket, but the two-piece recoil assembly requires a hex-wrench for takedown and I hate the ILS mainspring housing that Springfield uses. Plus, the ambi safety felt flimsy to me.
The Taurus PT1911 is overall a very nice gun, but the ugly billboards and the hammer-lock were a no-go.
The S&W SW1911 was nice but gaudy, and I prefer internal extractors and Series 80 FPSs.
The Dan Wessons I looked at were perfect in every respect; alas, the only ones available anywhere near me were 10mm, and I wanted a .45.
I ended up buying a Colt XSE Elite Combat, with a stainless frame and blue slide. It has one MIM part (the sear) and three cast steel parts (the thumb safety, Smith & Alexander beavertail, and the magazine release.) Everything else is either forged or wire-EDM'd out of bar stock. It has a really nice, "gun-like" exterior finish (not a fan of those thick, baked-on coatings, particularly on a 1911), genuine Novak sights, and it has been 100% reliable so far... no break-in needed. The only complaints are that the bottom edges of the slide are sharp, and there were a few burrs on the interior of slide. None of this affected the operation of the pistol in any way, but I did take a diamond-file to them. Also, the back of the plunger tube was a little loose, but red Loctite solved that.
The best part? It is built to 1911 spec to the point that it can be detail stripped with its own parts (I've done it.) It even has the proper slot-head grip screws that you can use a .45 ACP case rim in.
It was about middle of the pack pricewise (~$900), but I think it is an excellent value overall.
