Yes, Garuda does, even with bootable snapshots, but it’s otherwise not as clean as Endeavour. As far as I can tell, mkinitcpio/GRUB2 or their setup thereof causes more problems than it solves. My system was bricked multiple times until I switched to a dracut/systemd-boot setup, which works flawlessly since quite a while.

As for the user experience, there are 0 distros you should perform a (major) upgrade on without taking a snapshot first. I had broken systems after apt upgrade. From my point of view rolling vs versioned release are basically occasional mild vs scheduled huge headaches.
