Bevy has been extremely easy to use, although it still lacks a lot of features and has no graphical editor. I've used Unreal, Unity, Godot, and I was working for a while on a custom engine in C, and Bevy is by far my favorite so far, as it doesn't seem to lose performance for its ease of use, which was a big concern of mine. Rust is honestly a bit weird sometimes but I haven't found it too hard to pick up.
