We own at BWV and believe it the better of the two but I am sure most BCV owners believe the same about BCV. On a neutral note,you cannot go wrong with an Epcot resort for location -- boat and walking access to two parks, more than two dozen restaurants between the parks and the two parks, and nightly entertainment. BCV is closer to Epcot but BWV is only a few minutes longer and BWV has the shorter walk to Studios. As a BWV owner, you can get boardwalk view, one of the best views on site looking over the lake at Spaceship Earth in the distance. BCV has no premier views to speak of. BWV also has lower point cost standard view, for which, like boardwalk view, you also usually need that 11 month booking window, and those standard rooms, whose views are not bad at all, are the best bargain on site -- about OKW cost for premium location. BWV also has the advantage that the main pool is on the BWV side of the resort, unlike BCV where you have to walk over to the area between BC and YC. The BWV pool is good, although admittedly Stormalong Bay is the best pool on site.
Both the boardwalk resorts and the Beach Club resorts have good restaurants, and I am actually very partial to Cape May Cafe at BC but I do not look at the restaurants as a reason to favor one or the other resort because when going to dinner, you can easily go anywhere in the Epcot resort area from either BCV or BWV. The same applies to Boardwalk having its own nightly entertainment; you can also easily get to it from BCV.
Recently, the bus system changed at BWV. It now has its own bus to MK, where it used to share with Swan/Dophin. That change was one needed since BWV opened in the 1990's (when it also shared with YC/BC) and apparently my 17 years of sending letters and then emails, requesting that the bus system at BWV be improved (it was one of the worst on site) has finally paid off. Thus, though BWV is still not the best bus system, it has improved to likley be rated at least equal with BCV.
BWV's parking arrangement, with the lot some distance from the front of the resort is not as good as the nearby parking you can get at BCV. Also, BWV can at times, like when there is an event in the convention facilities at the resort, have parking issues with the main lot being filled, requiring parking in more distant satellite lot.
As to resale prices, BWV is generally lower than BCV although these days the difference between the two has been shrinking. One of the main reasons for the price difference is just historical. BWV opened several years before BCV and most of the original BWV owners paid an average price per point about $15 less than those who later purchased BCV with the result that a spread has always existed in the resale market because BWV owners do not need to charge as much as BCV owners to break even or make a profit in the sale.
