As an avid godot dev, the only gripes that I've had with it are a) merge conflicts can be a nightmare (but you can use git unlike unity sooooooo) and b) it lacks some deep control, but I was just able to fork it and implement it myself lmao.
It's actually really polished imo. It's sleek, minimal (compared to the others in its weight class), only 100mb, and development is just accelerating.
Me who programs in rust which has a specific compiler message to tell me what happened
