I want to run a membership site. Is there benefit to using Buddypress as well as the Membership plug

Ok, the vision is to have a membership site with 2-3 levels of paid access, as well as the opportunity for members to communicate with other members (forums would be preferable, PMs are ok).

I understand that Membership will cover the multi-levels of access.

Should Buddypress be incorporated too, or is that doubling up?

Also, hoping the entire site will run on Genesis framework, so compatibility here is to be considered. (Although happy to be talked out of Genesis if necessary).
