Godot is not a fast 2D engine, but good enough with many 2D commercial games.
Like Armory having a fully integrated 3D editor and tools (Blender), Godot has fully integrated 2D editor and tools.
You don’t need to re invent the wheel.
The choice will depend on the user preferences; how many features and tools he is ready to code ?
Someone will need the fastest 2D framework, another will just need good enough speed and will prefer more tools and features out of the box.
There is no universal choice LOL.
For some people Godot is better, for others Ogre 3D is better , for others Armory is better, and that’s their preferences.
Even writing hundred reviews or saying a feature on one is better than in the other you won’t change someone preferences.
What to say ? LOL
There is no universal formula, use with what suits you the best
