Looks like TunnelRat already answered most of the questions, but as for this one:
That's only that I prefer the 226 platform(9mm) to the 220 platform(45acp). I really like the way the 220 feels, but I've never been able to shoot them well. I don't know why. I shoot the 226 and 229 very well. I'm very interested in getting ahold of the newer P227 (double stack 45acp). Maybe the grip ergonomics being similar to the 226 would help me with shooting it better.
As for why I prefer the DA/SA to SAO - it's just what I've shot and am more comfortable with. I don't have a problem with the transition between trigger pulls. I guess it just 'makes sense' to me. I think if you're coming from a 1911 platform, then obviously the SAO model makes sense to you. I'm actually not a big fan of 1911's either. I love the way they look, but they feel awkward in my hand. I know that I am definitely a minority in that one.
I also think the Browning Hi Power is absolutely hideous where everyone else loves them. *shrug*
