The question of the ages? 
Pimax 5k+ looks like a clear winner, and also has the wider field of view. The drawback is the drain on the GPU, I'd love to hear if anyone has tried it with anything other than a top-end GPU on AFS2. With new headsets coming out soon, the compromise is going to be between clarity and field of view. The likes of HP reverb and Acer Ojo ConceptD will offer much better clarity for reading gauges, but not much improvement in field of view. A larger field of view is better for immersion and I suspect will make the world of difference when flying the R22. Valve Index is still a bit of a mystery. Rumous say that it will have a resolution of 1440 X 1600 with a 135 degree field of view, but this would make the clarity awful, far worse than the original rift, so does not make sense. Just have to wait and see.
I was surprised that the Odyssey+ looked better in most of the comparisons (PIMAX screen door was noticeable) - Odyssey was definitely the worst in the text comparisons.
I have Odyssey OG and Pimax 5K+/8K. 5K+ and Odyssey have almost the same, but 5K+ has more clarity over Odyssey, and the instruments on 5K+ are more readable.
