Gentoo

Overview
Gentoo offers ridiculous flexibility with the operating system at a price. It’s made for advanced users who don’t mind getting their hands dirty with the system.

Package Management
Gentoo uses its own package management, Portage. The Portage package management is very modular and easy to maintain, which plays a big part in the operating system as a whole being very flexible.

Configurability
If you’re just getting started with Linux and want to take a more difficult path, I’d choose Gentoo or Arch Linux as your distribution.

Uses
Great for desktop and laptop.
