Wouldn't that have more to do with the glass quality than the size of the enclosure?
I am not an optical engineer and while glass quality does play a part the larger the lens the more light can come through (at least that is how I think it works)
The FOV on a PVS-14 is pretty narrow which makes thick walled optics take up a lot of your vision. It can also create a blur around the optic where the enclosure is since the NVG is a fixed focus. You end up seeing a black, blurry ring around the glass which can mess with your target acquisition. Maybe the quad tube NVGs don't have this issue.
Glare is amplified when using NVGs so nice glass and a shroud helping block incidental light helps a lot. You can tell the difference between a Vortex's and Trijicon's glass.
Glass quality is fairly important with NV for clarity/IR transmission.
Yup. There's a loooooot of whys in that but if you want long range NV, a mounted scope is the way to go.
Coincidentally I just saw his channel and have been watching his ARG analysises and they are really good.
His first videos included guntuber tier-lists and a brandon herrea cosplay

Oh, man. That 2nd Amendment Audit at the Subway pissed so many people off.
