If you look at YouTube there are several videos that say distro does not matter, some of them possibly tongue-in-cheek.
Some say that the desktop, or presumably a window manager, is more important. Hence, we have Ubuntu in flavours like Kubuntu, Xubuntu and Lubuntu.
Then there are derivatives of Ubuntu like Linux Mint
If you love Black Arch - why???
Does it do something that you can't do with another distro? Say, for example, Slackware.
What unique qualities does it have?
(I'm not talking about saying it will boot 2 seconds faster than XYZ Linux.)
