BWV has the option of standard view rooms, which cost less points than the preferred view rooms. BWV preferred view rooms cost the same as the rooms at VWL. There is only one category of rooms at VWL.
Also, BWV has a special category of preferred view for rooms with a view of the Boardwalk. These rooms are very popular and can now be "guaranteed" when you make your reservation (subject to availability).
You'll need the 11 month booking indow to be assured of getting either a standard view or a Boardwalk view. Both of these are occasionally available at the 7 month window and there have been reports of successfully using the waitlist process to get these room categories, but that is the exception to the "rule".
IMHO, you will be happy no matter which (VWL or BWV) you choose - they are both wonderful places to stay.
Best wishes
