I really enjoy BtrFS, I don't know anything ... but since I used openSUSE for the first time with BtrFS and Snapper by default ... I never wanted to use ext4 again.
And I was so mad that default Fedora doesn't come with a Snapper layout or Timeshift layout by default ... why do they even use BtrFS on Workstation? Even RHEL uses XFS iirc. But at least the atomic spins make use out of it..
