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.
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-...
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.
