Superior parts, workmanship, and function. They're hard to beat in any of these areas, and having owning one that punches 2" groups out to 50yds with me behind it I can tell you I have no regrets in spending a couple grand on one. I've only ran about 1200-1500 rounds through mine but have yet to have a hicup of any kind. They're just not your typical off the production line type of 1911 - no mim, no BS, just one fine peice of workmanship.
