I don't think graphical fidelity is a good argument for any engine today. People are making movies with Unity[1] and Godot has demonstrated[2] all the bells and whistles you could want at least if you intend to target consumer PCs that exist today.

That being said, I'd imagine in a benchmark of GDNative vs Unity vs Unreal Unreal would probably win, Epic has way more than enough cashflow to throw tons of engineers on optimization that Godot just doesn't have. It wouldn't be an orders of magnitude difference, though - we are talking optimization of already tight render loops, and Godot benefits highly from having a tiny renderer.
