For what I understood, Funtoo is a bit less "in your hands" than Gentoo. Like if they were programming languages, Gentoo would be like C and Funtoo would be like Python (I know it's not a fair comparison, I'm just trying to be understood by a silly example).

Gentoo lets you customize just about everything, but it seems like with Funtoo they take a bit of that control ability out of your hands so you can have a functional system without needing to think so much about the minutia of installation and the like as you do with Gentoo.
