If anything I would imagine the 1-pc driveshaft moves around less than the 2-pc.

True story! I don't mind the extra vibrations, since the AL unit is half the price of the CF one and the cf is only about 1lb lighter. Plus I dunno, makes it feel more "racy". I'm weird in that I like my fun cars to be slightly uncomfortable like that.
My bad with the word choice, I didn't mean to say the AL shaft is actually moving around more, I mean more like there could be more play between it, the diff and the tranny on a sharp turn. My thinking was the factory one can flex at the joint so it copes a bit better with that sharp turn/accel scenario, where the AL one shifts slightly but just enough to rub one of the underplates. I could be way off though, wont know for sure till I get under there.
