Oh, I don’t think anybody will disagree that Unity is completely unoptimized and barebones compared to Unreal. It is also hard to learn and confusing compared to Godot.

There used to be a huge amount of people that wanted exactly something easier to learn than Unreal and more featureful than Godot. But those two improved in a way that this niche may not even exist anymore. Anyway, currently Unity has that unbeatable marketplace, and I really don’t know if there’s a good enough replacement somewhere, but I don’t see any other reason to use it.

(But then, I’m not really a game developer. I’ve used those here or there, for fun.)
