So? I've seen a lot of reviewers comparing them side-by-side too and they do see a great difference between both device FOVs. When all of them (as far as I've seen) all say that there really is a difference I just find it highly doubtful when you're saying the exact opposite, considering you said the FOV on the Rift seems bigger in the first post. Although that was before knowing about being able to adjust the lenses, which leads me to think you kind of 'reviewed' them prematurely without really knowing what one or both devices are really capable of. This is not criticizing you for having an opinion, but when 9 out of 10 reviewers says 'this' and you 'that' I find the other 9 more believable and I think you missed something. To be honest, it's not even a matter of opinion, it's a fact that the FOV on the Vive should be bigger (considering the specs/hardware and HTC empathizing on the fact they did it for being able to see the floor in Room play), so I believe the lenses are not set up correctly or both devices must sit on your head really different from each other.
So go buy one and tell me what you think comparing them side by side. Whether the internets say the sky should be falling or not, it's identical as far as I can tell in ED. But if you don't want to believe me, that's your opinion, but no matter how much you say "the internets say you're lying" - I can't discern any appreciable difference.
If you've already got one and not the other - it's irrelevant, you have what you have. Either way - it's not going to be a big enough reason for you to choose a device.
You either want the Room scale, or you don't.
You either want built in headphones, or you don't.
You either want the Vive controllers, or you want the Rift ones later in the year.
You either have space for room scale or you don't.
Those are the factors which will lead you to a purchase decision most likely, not a couple of degrees vertical FOV.
Not sure what your vested interest is in telling me that what I'm seeing with my own eyes in the actual hardware is wrong. Maybe the other reviewers are wrong, maybe they didn't use exactly the same experience to compare them - I've made very sure I'm in the exact same VR experience, in the correct place, with set references, for both comparisons. I'm also 100% sure I have the headsets configured correctly. Do you have a DK1/2/Rift or Vive? Anyone who has used VR knows that the experience can be quite subjective, and many different people don't experience the same thing.
I'm going to stop bothering reviewing these any more, because people telling me that what I'm actually observing is not what I'm observing is getting tedious. I'm not some VR newbie, I've built Unity games using the DK1/DK2, built engineering visualisations using them, I know my IPD, and I know how to set up and use both the Vive and Rift.
So - take it or leave it, or even better - go buy one or both, and see for yourself.
