Majaro (which is basically Arch+XFCE) is really slick looking. I'd use it as my primary if it weren't for HIDPI issues.

I switched to the Manjaro + XFCE from Arch + XFCE with a hope to get a more stable system since Manjaro team does addition polishing and testing. XFCE is a kind of simple DM in comparison wit Gnome/KDE, but powerful enough - so less chance of problems due to a lower level of complexity.

MATE in Arch then ;-)

MATE came from Arch originally, as it happens.
