I think you're suffering a bit from this: https://xkcd.com/2501/
You know the feeling you have about Gentoo? That's the feeling for someone going to Linux, even to Ubuntu, the more complications you add the worse the feeling is.
Arch is not hard, it's not complicated, but there's a lot of unknowns unknowns that can bite a newcomer in the ass. If you're already familiar with Linux Arch is easy peasy, just like Gentoo, it's just some small things you have to learn.
Think about it this way, you're already familiar with 99% of what Gentoo will ask of you and still it's not something you're up for doing, imagine the frustration of not knowing what's anything and having to go through that.
