The truth is it is confusing and the more you hear the worse it gets. people who have bad experiences with A will tell you to get B and vice versa. Worse still, some guy will have A and go on and on about how much he likes it which still has little comparative worth. There are a handful of people who have owned both and they might be able to help (assuming they bought their pistols somewhat recently esp w Kimber, which was much worse years ago).
I an a 1911 snob and don't have either. Both of them are mass-produced 1911s with a small chance of being lemons, and a good chance of being a great reliable shooter. Both have MIM parts. Both have alot of fans and disgruntled (former) owners. At the end of the day, it's really Ford v. Chevy. I would look at the features of the two for starters and see which you like best. Also you can inspect the pistols so look at fit and finish, as well as trigger pull. Absent of shooting them, that's about as good as it's going to get.
