I don't know much about the topic, but my understand was that bison graze more selectively, and have behaviors where they roll in grass, creating dirt ruts, which provides habitat for insects etc.
Bison are far more unruly though, so you need serious fencing to keep them contained, so it's less practical. I think they are lower maintenance than cattle, but bison just doesn't have the market.
