The 229 might actually be more snappy as the Sig has a higher bore axis and less slide mass than the G22.
As for the Commander 1911, that's a totally different animal than the other two guns you mention. I would probably advise either the 229 in 9mm or the Glock 19 before going to a totally different platform if you are comfortable with the operation of the Sig and the Glock. While I still feel that the 1911 is a find choice for a first time firearm, it's generally more costly and takes a little more dedication to get to the point where it should be carried.
If you plan on carrying the 1911, you need to practice much more in order to be able to remove the thumb safety on the draw unlike the "point and click" interface of the Sig and the Glock.
