From the selection, sounds like you are looking for a competition pistol. In which case, my vote goes for the Colt Govt. I have a Colt Combat Elite which is lightly modified for IPSC (back when I had the time to do so about 10 years ago!). The Colt was a great gun, although it is a series 80.
I also have a P220, the brisk recoil and DA/SA trigger are not conducive for competition, although it would be my first choice for a carry gun if we ever get the chance to do so in Kalifornia (super highly unlikely). I am not familiar with the sport model per se but it looks like it has the same pinned slide and aluminum frame as the regular P220, so I suspect it is not as tough as a 1911, but I could be wrong.
But if you already have a limited 1911, the P220 sport sounds like a great novelty gun to have in the safe!
