Megalomaniak yeah, most devs work in 2D and those who try 3D don't know what they are doing or don't read the docs.
there's also the problem of assets, a game with good assets will look good, a game with lower quality assets, like what a solo dev is able to do, will not look as good and some people will then see these and say that godot has outdated graphics (like what happened with road to vostok, the dev isn't even using PBR).
when in fact godot is closer to unreal with its Standard disney PBR and things like SSS and volumetric fog. It has more features than unity and most of the systems like retargeting and IK are just better.
I'm able to hot swap meshes in the editor and in game, where in unity this is impossible and breaks the SkinnedMesh, with the only solution being to prefab the meshes after importing everything in the same file.
This also allows for working on different parts of a character in different files.
And GLTF is just superior to fbx in every way.
