You literally did the same but the opposite way with this topic.
The closest fair comparison video was removed from Youtube (forest and village with optimised LODs masked material vs the same scene but with poly only Nanite). The guy literally took the time to test it for his game and see what’s better, not just a random scene. And concluded Nanite was better. Not only it looks better but upscallers works better.
Moreover 5.6 have big performances improvement for HWRT lumen and virtual shadow maps so it works even better with nanite.
