Not really an apples to apples comparison. One is a timeshare resort with a management company (SVR), the other (WH) is a vacation home community.
You will probably have more space at WH, possibly your own pool, but each unit is individually owned and furnished; make sure you are happy with the specific unit you are getting at WH. The downside is that you will generally have to do more cleaning on departure, and I don't think daily housekeeping is an option; but I stand to be corrected. Our family is timeshare all the way, so haven't personally stayed at WH!
At SVR it is more like a hotel in the sense that all units are equally equipped, there is housekeeping available (although most people stick with the standard mid-week tidy and towel change), and there are more amenity options. If you are seriously dissatisfied with a particular unit, there is the option of being moved to another unit. There are lots of different pools on resort (7 of them!), but you won't have a private pool. There are dining and shopping options on resort.
