I think the SL6 is gorgeous, but aesthetics are a very personal thing. I'm also a bit biased since I opted for an SL6.
As OHrider mentioned, the SL6 uses the more standard 12x100/12x142 thru axle setup, and flat mount brakes. The Comp/Sport frames also have a threaded bb (Pro/Expert/S-works are press-fit).
Just finished building my SL6 Comp last night, just need to do the bar tape today and take her out for her first ride. I HIGHLY recommend the Park Tool IR-1 internal cable routing kit. The shift cables were actually pretty easy, but we used the IR-1 to route the hyd hoses and it was a lifesaver. I can't even imagine trying to route the rear brake hose without it. We had the whole bike built in a few hours, not even a single swear word was uttered.
