From what I could gather the resolution on the Rift S is 1,280 × 1,440 per-eye (2,560 × 1,440 total) and the Quest is 1,440 × 1,600 per-eye (2,880 × 1,600 total) [0], shouldn't the one rending on a desktop GPU have higher resolution? Maybe the source is nor right as it's slightly outdated, but I couldn't find actual numbers in the website.
Also, it would have been nice to get the snap855, but probably would have made the headset a bit too expensive for the target market. The only thing that is miles ahead of the Go is the tracking from what I can see. Not worth updating for how little I use it.
The Go is 3x3 (3DOF HMD, 3DOF simple controller) and the Quest is 6x6 (6DOF HMD, dual 6DOF touch controllers) which is a quantum leap of a difference.
While the former is only good mostly for 360 photo/video and some not-so-immersive experiences, the latter lets you basically have VR experiences w/ with full hand and head tracking on par with the best PC VR out there. I have a CV1 and a wireless Vive (a Go and Focus as well) and I'm incredibly impressed by the Quest - the polish on the setup/intro app (the dancing robot is my new favorite demo showcasing the potential/visceral impact VR can have), and personally, I think the Quest is the first true "mainstream" ready VR product - I hope everyone at least tries it for themselves before completely dismissing it.
In physics, quantum leap is used specifically to describe discontinuous state changes, which is why I like the term - IMO 3x3 vs 6x6 are almost completely different mediums experientially (that'd be its own conversation), but your comment did lead me down a bit of a pleasant linguistic-curiosity rabbit hole as I double checked, since I can see why "quanta" might imply something small, but colloquially quantum leap does not.
