From what I played of the demo (compared to the full version of Ninja Gaiden Sigma), Sigma II is WAY better. It looks better, runs better, feels more polished, and of course has Sixaxis implementation 
I still won't get it, though, because I sucked so hard at the first game that I couldn't beat it on Easy.
