That is a large part of it. The other factor is that there are no exposed runs of chain to deal with.
I do not think 2791's drive is "better" than a traditional WCD, and the benefits of putting belt inside the tube rather than outside are somewhat marginal, but it works well for us and there is certainly something special about a drivetrain you literally never have to adjust.
