This may go against the grain a bit, but my STI DVC OMNI is the tightest fitting, smoothest shooting, with the crispest trigger of all of my 1911/2011s. For a "production gun, with production quality" it blows some of my higher end guns out of the water. Some guns maybe have more soul (like my alchemy's) but nothing I have performs better in all quantifiable metrics, at least with my particular pistol.
I can run it with .11 second splits doing double taps in the A zone at 15 yards. It's an insane pistol.
Now I haven't handled an XC, nor do I really know how meaningful the difference between STI/Staccato's rebranding is, but if it's anything like my Omni, you will be completely satisfied.
I'm getting in a Firehawk soon, but it'll be in 45 so it won't be the best side by side comparison, but I'm happy to report back on my findings.
