Arch Linux because it has sane defaults, is rolling, up to date, helpful community, awesome wiki and is minimalistic.

OpenSUSE Tumbleweed. I like it for being a rolling release with quality control. On the one hand I don’t like its restrictive defaults but on the other hand I know enough to work with them and that’s given me a leaner system.

Relatively fast updates, AUR, PKGBUILD, Downgrade, the Wiki, the community, not controlled by some corporate entity, no telemetry, and last but not least the logo ;)
