You nailed it on the head. The Quest is a nearly "do it all" VR device. Do you want a mobile VR experience to enjoy with friends on the go (streaming to a TV/Phone)? Check. Do you want to experience the high quality (graphics) of a high end VR experience, you can do that too (both wired and wirelessly)! Aside from the refresh rate which I personally have no issues with, I can't see any reason to purchase a wired PCVR-only headset.

And just to comment on the Oculus Quests SDE (screen door effect), this has been greatly been improved. I honestly do not even notice this at all like I did with the Oculus Go.
