I am trying to decide between a WPC or SPC vinyl floor in my new home. We are in our low 60s, so WPC would be better for our joints, but there will be a 4 season sunroom and most windows in the house will face south. It will be in the Northeast, so not crazy hot sun. I also am worried about denying the WPC too easily. For those of you with SPC, do you find it really hard? Has it dented easily? If you have had both, which did you prefer?
