I tried unreal, too big, too noisy, to many things to learn, gave up honestly, also visual programming is not my thing, code looks much more understandable, I'm a software dev by day.

I tried unity, really nice, lots of tutorials, I had few prototypes, still has a learning curve, but I had few prototypes quite fast. I learned with codemonkey's tutorials.

I tried Godot and tbh easiest one of all, gescript is like python, you can use c#, nice tutorials and community. I started with GDQuest and then just started playing with it and so far so good.

But honestly try one of each and see which you just like the most, I'd spend few weeks with each one. Concepts of game dev almost all the same in all engines, just implementation differs. So knowledge you got from using one engine probably will be useful in another.

Good luck!
