And, lastly (for me), it has a pretty small footprint. Godot is like 45 MB. And when I run it, I don't have to have some account somewhere, it doesn't have to check in.
That's something that suprised me and I like about it. It's just really quick to get up and running. I mean, I wouldn't see it as a problem even if it was 500 MB (which would still be less that other engines), but the portability and quick start-up / loading are great.
As for how well it handles and performs, I'm not sure. I didn't spend much time with it, yet. I'm a bit concerned about performance (of the 3d graphics in general, aswell as some of the scripting methods like GDScript or the visual coding feature) but these might be no problem at all.
