Hmmmmmm, this is a tough one. I have owned or shot all of the above. I have seen examples of each that will shoot 1 1/2" groups at 25 yds. I have also seen all of the above shoot 5" groups at 25 yds.
My advice would be to handle all of them (and better yet, shoot each of them, if possible) and get a feel for each of them. Often, a gun will simply "feel right" in your hands, and you will instantly know that you have found the gun for you.
For that kind of money, you are almost into the semi-custom manufacturers' starting price. This is another option to consider, as Wilson, Brown and Baer offer accuracy guarantee options with some of their guns.
All that being said, my personal preference leans towards Colt. They are a good platform to build on, should you wish to add different sights and other options later on, and the 1991A1's often shoot surprisingly well right out of the box.
Let us know what you end up with.
