gollark: I use Arch Linux, which is rolling release (there are no fixed versions of the distro, you just update your packages whenever they get updated), very flexible (you install it manually, choosing partition layout, DE, extra software, etc), and has the AUR, a giant collection of user-packaged software.
gollark: Plus different stuff for managing services.
gollark: Many of them have different sets of available packages and stuff, or different package managers, or different desktop environments (you can usually swap them, though).
gollark: There are quite significant differences between distros, actually.
gollark: But I don't think it's the most common or easy distro.
