Gentoo Linux, a very unique Linux distribution
Gentoo Linux is a very unique distro, as it has a minimalist approach to computing, similar to Arch Linux. Gentoo is not for beginners, and installing it is a very big hassle, because you either have to compile source code to install it, or follow the official installation guide, which takes about an hour or more to complete, so there is no other way of saying this, Gentoo is freaking hard!
Still, its a Linux distro nonetheless, and I do recommend you try it out as a live system on a physical PC, or in a VM.
