Gentoo can be a double-edged sword. It’s probably the most customisable Linux distribution available, letting you build it from the ground up to be exactly what you want it to be. However, it’s not all that easy to get to grips with and requires some serious skills in Linux to get right.
Once you have, though, Gentoo can be very rewarding. Building packages from source and compiling the kernel yourself feels like you’re making the most out of your Linux experience, and can actually help make your system a lot faster than some of the more popular, preconfigured distros.
