Starting a martial arts association, should I use MU or BuddyPress

I am starting a martial arts association. Each member will have a page (Uniform design) with their photo, bio, a testimonial section displayed and form that submits testimonials for approval by the member. Their page will be example.com/AndrewK To do this should I use MU or a buddypress? Note the association has a monthly fee and if unpaid their site/page will go down until payment is made.
