your home resort tells you 1)
how much you pay in annual dues and 2) where you have a home resort booking advantage starting at 11 months out.
at 7 months, all points are the same. at 7 months, you will find it much more difficult to book standard view rooms at BWV and concierge rooms at AKV among others. VWL and BCV are smaller resorts that can be more difficult to book at 7 months as well.
if you're happy just to be onsite at wdw (or you can't book more than 7 months out regardless), then resale SSR pts are a great deal. if you would be disappointed to be "stuck" at SSR if a waitlist fails to come through...then you're better of "buying where you want to stay" (as we tend to say around here.)
