I think the general thought process is the greater weight out front of the bull barrel helps with recoil. I don’t have a 2011 without a bull barrel, so I can’t personally say one way or the other. I have shot 9mm 1911s and those seemed fine, but they also had a full steel frame. I think generally I want a bull barrel on a 2011. To be fair, however, it is 9mm in what are often larger, heavier pistols. The recoil is not that punishing to begin with. I know in this case it’s basically the same pistol with or without the bull barrel, but in other cases if there were other features different between the pistol with the bull barrel and the pistol without, those other features might mean more to me.
To the comments about bull barrels being easier to disassemble, I think that sort of depends. Some bull barrel 1911s/2011s are pretty easy to disassemble. Some require tools or at least a paper clip or similar. To me that’s more work than rotating a barrel bushing, at least if the tool isn’t something I normally have on me.
