The quoted statement is 100% accurate. Unity is very slow. When I worked on Unity with a larger project, I'd often have to wait 10+ seconds for Unity to rescan the entire project every time I switched windows from my IDE to Unity, or every time I ran the project. In similar project sizes, Godot was always lightning fast.

> Godot looks like Unity from 2008, it's easy to boast efficiency when you have a limited product.

Unity does have more features - like more obscure 3D features - but that has nothing to do with how Unity deems it necessary to rescan the project tree all the time. Also, when I used Unity, I never used these extra features, so even if this were true, how come all users have to pay the price for features that only a few of us will use?

Honestly, core Godot is very full-featured, and in my experience the central abstractions are much better thought out than those in Unity. I feel a lot of the FUD around "Unity has more features than Godot" comes from people that like seeing a long list of features, not from people who actually need those features.
