Linux Mint +1.
When I do a Linux Mint install, during the partitioning step, I chose to set the root partition as type BTRFS, not the default of ext4. This way, the Timeshift app can create and restore to BTRFS snapshots. These snapshots provide a mechanism of safety, somewhat akin to how an immutable distro provides a mechanism of safety/fallback (in case something goes really wrong, and you need to do a "roll-back").
I've been using Linux mint in this way for about 6 years. BTRFS has never once let me down. (I've also used BTRFS on fileservers, and love the subvolume snapshotting features, just saying.)
