My question is... Which is easier to use keyboard with? Do you have to remove the head set to see the keyboard? I cant type without looking, hand numbness, but never could even before the MS caused the numbness. I don't get out much and ha vent been able to test drive VR. I did see some where, that one of the platforms Vivie I believe was working on "hand trackers" controllers? Most of the reviews for that platform stated that most were waiting on that upgrade before they took the plunge. I love my TIR but this VR 
if I can find one that can work with my particular disabilities would just be awesome! 
Well from what I know of now you cant directly see the keyboard from Oculus nor the VIVE, HOWEVER, the HTC Vivie does have a camera on the front outside that you can set to toggle on/off with a button. The camera has a weird blue effect, almost like looking through a thermal camera or something off of a ghost adventure show
The benefit of using that sort of low blue lighting effect is that it doesn't expose your eyes to bright roomlight if you happen to be running the game in lower gamma settings or in a dark area and it would force your vision to constantly readjust in a negative way.
I am not familiar with which system is working on hand tracking for a VR keyboard, but the HTC VIVE comes with two handy controllers that you can choose to use or not use. Sometimes I used them for a while when I first got the headset but most the time I just use the mouse and look at where I want to click with my head on things on the clipboard. I have the advantage of having been taught how to type with my keyboard being covered and at times the monitor too! My teacher ran a keystroke detection program so she would penalize us for hitting the backspace too often. I'd say most people with confidence and an ability/will to learn will find that once they get their hands set to homekey orientation they will type just fine, however health issues like you've described could be a real challenge.
You can always lift the headsets up and rest them on your head to see they keyboard for typing while on autopilot or in the hanger. The VIVE ways a little bit more than the Oculus but I like its head harness better.
The VIVE has an analogue cord on the back of the headset to plug in earbuds (and comes with some OK ones) or some other stereo speakers while the Oculus comes with some old school looking ear speakers. Not sure about the Oculus but the VIVE has a built in mic that works very well and the headset itself can also be adjusted for using with glasses and such.
Hope the info helps out a bit more!
