Colt 1911 conundrum

[flphotog]

I'm looking at getting a Colt commander this year, mostly because I want another commander for carry and I don't yet have a colt.
My early preference is the XSE series but I'm only seeing the commander in brushed stainless which isn't on my personal hit list.
So I looked at the 1991 series, there is a blued one there but I don't care for the sights but that at least can be fixed.
Does anyone have any input on other differences between the XSE series and the 1991 series?
