Oh man, I just started learning to use vim yesterday!
I think in terms of capabilities and speed godot is pretty simple to start with.. I'm no python programmer and I found it really straight forward with the syntax (I've never really tried pygames before though...)
It's pretty powerful nowadays so I would definitely recommend getting into it. Also a ton of new and good tutorials now (especially since the unity crises...)
