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.

Off topic: a quantum leap is a very small leap. The smallest possible.

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.

quantum leap [n]: an abrupt change, sudden increase, or dramatic advance https://www.merriam-webster.com/dictionary/quantum%20leap

Apparently the term "quantum leap" gained popular use in the 1930s and over time (starting in the 50s) acquired connotations of being very big: https://www.vocabulary.com/articles/wc/how-did-quantum-come-...
