What I love most about Godot is that it doesn't give a fuck whether you want to use python-like code or write your own libraries in C#/C++. 10 minutes and you've got something working.
I can't even imagine how that backend must look, 🤣 I work 100% in GDscript, but it's really cool to hear : "Yeah it's about 30% GDscript and 70% C++"
Coming from Java, I personally love how signals work between classes. Friggin hated my getters and setters, and the way signals work in Godot is just like how my brain thinks about that problem, so very easy to use and understandable.
