The really critical items for you to consider in making your home resort decision are airfare and the usual lead time you have to plan your vacation.
Since we also have to worry about airfare, I want/need to know my lodging is set as far ahead of time as possible. That gives me time to find a sale and lock in the best airfare. (Can't afford the "usual" prices from MSP-MCO, LOL). The 11 month window is important for me as I cannot stand the "stress" of worrying about whether or not the waitlist will come through for me. If you really don't want to stay at VB if you can't get a WDW ressie when you call, and don't want to wait for the waitlist to possibly work before you book non-refundable airfare, then you do need to "buy where you want to stay the most".
FWIW, if you mostly plan to travel in the summer, I don't think you will have a problem getting a WDW ressie less than 7 months ahead of time. It's actually easier to get in the WDW
DVC resorts on points during the summer than in some of the "slower" (lower point) seasons.
If your circumstances do not permit you to plan more than 7 months ahead of time (maybe a job or kid issue), as others have said, the 11 month window doesn't matter. Buy where you think you can get the best deal.
I do agree that VB may not be the least expensive to own in the long run. I expect dues to continue to be the highest of the DVC resorts (due to extra expenses of maintaining the ocean front property) and also for them to rise faster than the others (same reason). However, VB is a beautiful resort and if you ever want to stay in one fo the Beach Cottages, you will need the 11 month window to get one. If you haven't seen the Beach Cottages in person yet, just wait! They are truly gorgeous!
Have fun making the decision!
