Neither does anyone else. "Best" is very subjective.
Your options are:
$ < $500 = Rock Island Armory, or base model Springfield armory. Both of them are generaly good guns, and both of them have fans.
$501 - 1,000 = high end Springfield's, Kimbers, and Dan Wesson. Also good guns....but most of them are specialty models or entry level target pistols. Id say that the Dan Wesson guns are the best USERS in this category, but they are all good.
$ > 1,000 = Night Hawk, Ed Brown, Wilson Combat, ect. These are fancy over-the-top super match grade guns that cost a crap load of money, and much of that cost goes towards the label. They will all shoot very small groups, and have the unique ability to make elderly men fawn over them... They also have a reputation (deserved or not) of failing multi-day pistol course.
But admittedly, iv only owned one 1911 in my time, and its a user model, not a target pistol. I don't know much about them other than how to detail strip, clean, and hit a target with one. I'm not up on all the latest wiz-bang features and design tweaks.
