@smokinhole. For DCS in particular, everything I have read has suggested that the Rift is the better headset. Lighter, more comfortable, better optics (larger sweet spot and less screen door effect). The Rift also has integrated headphones which seem pretty good to me (and it is extremely convenient to have the headphones as part of the headset itself). It is considerably cheaper than the Vive as well.
Another factor is that the Rift has a small nose gap. That might sound like a disadvantage, but in reality, it allows you to glance down over your nose to see just enough of the keyboard that you can use it. I am able to jot down a 9 Line in this way too. As soon as you look up again, the nose gap is invisible, so it isn't an immersion killer.
So, if room scale gaming isn't your thing, the Rift makes more sense. The Vive does roomscale better by all accounts, although the Rift roomscale experience is pretty darned good in my opinion.
Personally, when it comes to what company makes it, I don't really care. I just want the best experience when it comes to what I want to do with VR, which is cockpit based sims. With the current gen headsets, the Rift wins in several areas (AND it is cheaper by quite a margin).
The Touch controllers are very cool. Great for shooters, The Climb and also Google Earth VR. I am not sorry that I bought a set. They come with an extra sensor as well, so they are excellent value, but at the end of the day I don't use them a whole lot.
