Don't know too much about Godot but I'd imagine something like this is more suitable for making an RPG simply because its got all the tools you'd need in an RPG game (stuff like dialogue etc) so the developer can just focus on making an RPG rather than having to worry about the specifics of how dialogues are displayed, and stuff like that. Whereas I think Godot is more just for making any type of game, and in that sense will be more powerful but will lack the tools for building a specific type of game like EasyRPG appears to provide.
I don't know about this tool specifically, but rpg maker was good at making rpg maker's style of rpg (ie. traditional 2d JRPGs), not every kind of rpg.
Going toward action rpgs like Zelda III wasn't impossible, but quite difficult.
Going towards things such as baldur's gate or diablo was pretty much out of the question.
