we own DVC at both BCV & BWV (as well as SSR).
BWV wins, hands down
we prefer the views at BWVs (we looooooove BW view

~ sitting on the balcony, sipping coffee, & watching the BW activities in the morn/afternoon, and/or watching illuminations from the balcony in the PM

. ). or you can save points with a standard view (both BW & standard views do go very quickly ~ the 11 month advantage really comes into play

).
all the views at the BWVs are outstanding tho, imho. & we actually like the clown pool better than SAB (yup, there are some ppl who do! lol )
there are so many activities going on the BW itself: street performers, hair braiding, surrey bikes, jellyrolls, etc. btw, except for walking over to EPCOT for dinner, we spend little time in the parks when we're at the BWV ~ it's a vacation destination unto itself, IMHO
BCV is beautiful, but we (DH, my kids, DPs, DB, DSIL, & newphews aged 6 & 9 at the time)
greatly prefer BWV. all of us (on different visits) found the BCV's very noisy, SAB very crowded, & lacking worthwhile views ("EPCOT view" was of a road, a lot of tall trees, with an ocassional
very high firework

). also, there is only one view catagory (the same amt of points as a preferred/BW view, no point-saving standard).
the one thing that bothers some is that the BWVs lack a full counter service location (there is the delicious BW bakery

, but it's limited), but that is one of the reasons we like it better

. we find there is less external traffic thru the resort itself, lending to a more elegant atmosphere (fun, but still elegant). there are also other food options: pizza window, spoodles (excellent food), ESPN, big river grille, as well as a few different goodies
btw, the YC is our favorite non-DVC resort (over the BC)
you might want to consider posting your question on the DVC misc board tho.
