[ParadigmComplex]

Bedrock Linux, as it gives me many of the advantages of other distros at the same time. Stability of Debian/CentOS, access to cutting-edge packages from Arch (including AUR), ability to have portage automatically compile things with my preferences from Gentoo, library compatibility with Ubuntu for things like steam, etc etc.

Note: Main area it is lacking is the "just works without setup"; it does not compete with Ubuntu/Mint/etc on that front.

Full disclosure: I'm the founder and lead developer.
