That's one distro that I never ran. I almost ran it because my friends that ran an ISP 20 years ago had this bad ass mail cluster built on Gentoo and the dude behind it, Lindsay, was a baller. He was a huge fan of Gentoo.
I've ran RedHat, Fedora, CentOS, SUSE, Debian, Ubuntu, Mint, Elementary, Arch, Knoppix, and probably others that I'm forgetting.
