I bought a fancy PC, a Vive and the Rift to play with them and see how the tech is shaping up.
The Rift may be better now given Zuckerberg's demo and the shipping touch controls, but I ended up selling it. Playing with an Xbox One controller was a pretty bad experience (with the one exception being the space game) and it was overall pretty disappointing compared to the Vive.
The Vive with room scale is something different - it's really impressive. The touch controllers work well and the movement feels natural. The content right now though is pretty limited and Oculus has tied up a lot with software exclusives.
Maybe Oculus will do well with the social stuff they're working on (demo was cool) and GearVR might save them, but the Vive is a much better product right now and worth playing with if you can.
