Better screen contrast and colors, and the ability to use it wirelessly if you set it up right with the right router. Also it has IPD adjustment, so if the Rift S looked slightly blurry in one eye or had a bit of eye strain for you, then that can be an advantage, but you ultimately can't know if that would've happened to you without just trying a Rift S, since IPD measurements are unreliable.
