Full caveat: I am presently not an Open Division competitor. I am not ranked within USPSA. I do shoot a lot of nice, fast guns with some really top tier shooters.
I went with a Czechmate Parrot because of cost and familiarity. I can work on CZs already, and I could afford to buy one since it comes with so many parts and mags. The CM is the most accurate gun I've ever shot. I'm sure there are 2011s and other guns that are at least as accurate, but accuracy isn't the question.
Speed? You probably have more options for getting the red dot closer to the barrel on a 2011 so that the aim is more natural, and you probably have more options for compensators with a 2011.
Reliability? People say that a 1911/2011 can be made to run flawlessly. I fully believe that. However, the Czechmate runs flawlessly out if the box, requires no magazine tuning, and is significantly cheaper than an equivalent 2011. This is also true for the Tanfoglio version.
Trigger? Does it really matter when going full speed? I can't tell the difference between a $5k 2011 and my Czechmate when going full speed.
