Slackware-current is pretty current. And sbopkg has quite a lot of packages. I run it on my homeserver (and has been for the last..10-15? years or so). Since everything that I host uses docker its easy as pie to keep it running.

ZFS via ZoL etc.

As a daily driver i use PopOs! which is very nice since the've packaged nvidiadrivers etc. and I mainly use it to play games.
