My order of preference from those I have stayed in is as follows:
Crestview - newer and nicer furnishings.
Ridge Top Summit (2 bedroom Deluxe units) - a bit nicer than the ordinary Ridge Top units. If I am remembering correctly, there is a jacuzzi tub in them.
Ridge Top - a plus from these is that some still have real wood fireplaces, but I think they are switching them out.
Depuy - Renovated units are not bad - the shower water pressure is great. I have not seen the units that aren't renovated, but the renovated ones are fine. The kitchen has a LOT of space, which is nice.
The Ridge Top and Depuy are older units, so there tends to be older decor, etc. They suffice, though, and are really more "in the woods" than the Crestview units. The bathrooms are kind of small. If you go in knowing you are getting an older unit, it is easier to be satisfied. If you are expecting Bonnet Creek style furnishings, you will be disappointed in any but Crestview.
I haven't stayed at Fairway or River Village, but I don't think I will based on reviews and just driving by those to see what they are like from the outside.
