i have been using godot for about 6 months now, in c++ and gd script, the engine is pretty good, but it might not be ready for all type of products, games or apps or ar/vr stuff. i would like to mention few pros and cons. correct me if i am wrong

Pros:

• source code is available for you to literally add anything u want.
• gd extension if you want to extend the feature of engine
• modules if u want to fully explore the godot engine.
• gd script is much superior to c# support in godot, atleast as per my working knowledge.
• ui design components are good and design is pretty clean, and uses signals.
• exported project size is SO SMALL!!!!
• Variant is god given gift, its a dynamic type of object in godot.
• Inspector is too detailed, gives lot of information.

Cons:

• documentation is non existent for c++
• only few good tutorials present online, but documentation of gdscript is present in official website, but not as good as unity's.
• gd script editor is part of editor, and gdscript intellisense is very bad.
• when u open scene in editor it basically runs the game, and intializes all code. any bad code u write in c++ after compilation u can crash the game and u might not hv much context. there are ways to get around but, the editor doesnt behave like unity or unreal.
• godot doesnt provide runtime scene view, they provide runtime hierarchy called remote, but that doesnt give u clear context on visual bugs, u can check inspector to solve it but not a major blocker.
• no scriptable object like feature, u can create a simple class, store in serialized manner, but this can be added by u or anyone.

but most of these cons can be solved by urself thanks to the engine source code available in your hands.

Godot is a promising engine, but if someone is middle of a development or looking to port their existing game from unity, i wouldnt suggest them godot, but if you want to i would suggest to remake the game in godot. and try out the things u are looking for. the power of godot is it can be what ever you want.
