I felt more inclined to move around while playing SR. Whereas uf I'm playing BS I focus more on hitting the blocks and the overall experience just feels more stiff in general. 
I think the devs of SR themselves said that they made it so it'd be relatively easy to get a full combo, whereas actually getting a good score is harder. You can kind of see it in this video.
