I compare scenery with the default rendition versus my "production" copy of X-Plane with multiple scenery add-ons and Ortho4XP scenery. To my surprise, the default scenery has come a long way from when I originally installed X-Plane 11.
I plan to follow-up with a video showing you some of what I've done to get my production scenery.
While this is a non-scientific comparison my method was to spawn into 3 vastly different airports to see what the scenery looked like in both X-Plane copies. Hope you enjoyed it or you'll enjoy it.
