Well, I have a 09' SCG, so I am partial to it. For commuting, the 1203cc displacement and gearing makes highway riding more comfortable than the Xb9's. As for compared to other bikes, I think it is probably more of a personal preference. I chose the XB for a couple of factors:
1. I owned a sportster prior so I am familiar with the engine and am able to wrench on it.
2. Ease of maintenance... No need to do more than fluid changes, clean air filter, brakes and tires as a matter of normal maintenance. The engine itself is a relative crude piece of machinery that is pretty bulletproof.
3. Character... Nice Harley rumble versus the high pitch whine of the Japanese bikes when putting around town. Also, so few on the road I always get people asking me what kind of bike it is.
4. Great performance on twisties. Shorter wheelbase and Erik Buell's trilogy of tech makes flicking the bike and taking those twisties super fun.
I do wonder if I would enjoy the 1125CR more with its higher torque helicon engine, but still happy with my XB.
