I have owned both skis, and skied on each for over a year. Both are very good skis. I do like the Vapor over the Quest. Both skis turn pretty much the same, however I feel the Vapor is faster to the ball, has a better glide on the pull-out for the gates. I found the Quest to stall out if you put too much pressure on the front foot on the offside turn. But like disland says you should try each ski, one may be better for your skiing style. Many of my ski buddies have gone from the Quest to the Vapor, and have sold their quest to other owners at our lakes and they are happy
with the Quest. I do feel my skiing progression sort of stalled on the Quest, this year has been one of my best ski years on the Vapor.
