Let me start off by saying I'm a DVC member and have stayed at OKW for years, so I may be a little biased.
However, this past Oct., we stayed in a 2 bedroom at VWL. Though I like the theming of the WL and the boat ride to MK, I really missed the space of an OKW villa. If you are looking at using a car and hauling your own groceries to your room, you'll be surprised at the walk you have at WL. Or you can have bell services take them to your room. The luggage dollies cannot be used by anyone other than bell services.
The VWL is beautiful and quiet. We had a woods view on the pool side of the building. The balconies are tiny and you get two separate ones for most 2br villas. The furnishings are all high quality. The 2nd bedroom was very nice and the vanity area was huge! (We had a dedicated 2br unit.) The VWL quiet pool is enjoyable, but the main WL pool area is stunning.
OKW has a much different feel to it. I like being able to park outside our building. Though the pool areas aren't flashy, I like the lushness surrounding the main pool and the toddler pool being adjacent to the playground area. As for transportation, though an OKW bus to MK isn't as exciting as a VWL boat ride, it can take about the same amount of time.
I guess you'll just have to determine what's important to you at this time and make your decision based on that. You'll probably get lots of people extolling the virtues of ones over the other. (I follow DVC boards and one resort vs. another sparks a lively exchange of messages!) Whichever one you decide on will be sure to please!
