With UE4 you have a very large engine to deal with. With Godot you'll spend more time making your game look AAA.

for 2D I'd definitely go Godot.

I mostly do 3D games with fixed or limited range cameras (not first persons) so Godot works nicely.

Overall you'll need to understand well the engine you choose going forward. They all have their pros and cons.

As an example, it takes 3-4 hours to recompile the UE4 engine source code (for customization). Godot, about 4-12 minutes, in its entirety.

In general I'd say Godot is excellent for the average indie game. It might not be the best choice for cutting edge AAA rendering or performance. In my experience the most important aspect of an engine for a solo/hobby developer is the ergonomics and the workflow. I've found Godot to be a breeze of fresh air in this respect compared to the much more clunky Unity or UE.
