At WDW (which I presume is your desired destination), all are very good. I consider the best to be the six at AKV Jambo, which are all single story units, and the 5 BWV single story units (5 of 7 are single story not the other way around). I highly prefer the single story units and I assume VGF's are probably on the same plain as BWV and Jambo but I have not seen VGF's.The BWV unit has one of the best views on site and a huge, open combined living room, dining room and kitchen that easily holds large groups very comfortably. AKV is not as open, including because it has a room in which the pool table is in, but it is still more space than the two story living and dining room areas and it has huge balconies, view of animals, that pool table room, and a very large master bath with its own wide-screen television to watch from the whirlpool tub. I found the BLT units also very impressive for two story units, particularly for the almost two story high windows in the living room.
Owners of a resort can book 11 months out and you can easily get one in Feb at a home resort that way, except that the OKW GV's in the Near Hospitality House booking category have a risk of being gone even before 11 months out, If you will be relying on the 7 month reservation window, when
DVC members can start reserving resorts other than the one they own, you will find BWV most likely gone for most of Feb, while the others should still be open with some risk otherwise for Jambo and BLT theme park view.
