In our opinion the JBV are best.
We loved the dolphin 3 where we stayed, it has a perfect east facing view, it's close enough to the jetty and the rest/bar/spa area, and best of all it's right on the beach, which you don't get on a WV, and since you spend so much time in the water, it's nice to be able to just sit and soak on that perfect white sand...
You also get the nice outside wc + jacuzzi, better than WV cause the wc's are inside on those...
in all, for us it's just the best spot of the island.
