My reply is the one you shoot better with, assuming both are reliable.
I shoot my modestly customized Colt 1991A1 GM better and more easily than any non-single action gun. The reason, the trigger.
However, I am getting a Glock 35. The reason, ammo capacity. I have also tried Glocks whose owners have done a little polishing here and there, and come up with smoother Glock triggers.
As an aside, I now sometimes carry my Glock 30 vs. my Colt, becuase of the clothes I wear. The Colt hammer can get hungup in sweaters during presentations. The Glock design minimizes this.
I was going to get a Glock 22, but the G35 came out. I did not like the G23 too hot; it did not feel as good in my hands as the G22.
