I've used both and the differences between the platforms are so small compared to the huge technological breakthrough that I think which one people buy will be a toss up. I bought the oculus because I have a one bedroom apartment and have maybe a 2x2 foot space to use it in. Room scale isn't really an option for me. I like the Vive, but I really think that room scale is a liability nightmare waiting to happen. In two weeks of doing demos at work, we lost two computers from people ripping the cords out or kicking them and at least one person got clocked with a controller while I was watching people do demos for an hour. (and this was with a full time minder) Encouraging people to move around a swing controllers while wearing a blindfold is a terrible idea and someone's child or pet is going to be seriously hurt, no matter how many warnings you give people.
