Rotating mass matters significantly in acceleration. Once you are going, it isn't different from non-rotating mass, though. More mass equals more stability - but it is less agile feeling.
Basically, the inertia you feel when you spin up a wheel in the air is what is added to the longitudinal acceleration. It isn't insignificant, for a tire it essentially means that the total inertia is double that of it's weight.
But once you are going, the impact is small. You'll not notice it grinding up a hill, but you'll notice it in a sprint.
