My only experience with it is on the pinephone, which was... interesting ('cool, linux on a phone!'), until the update system broke a couple months later. I've tried several times to fix it now and it's still broken. It's been 3+ years now.
I lost both of my mSD cards I have, so I can't even load an alternative distro until I find them, or pay another like $30 for another one.
EndeavourOS on the other hand, I set up BTRFS with grub bootable timeshift snapshots and have never gotten to use them once. In my experience at least, EndeavourOS is blatantly superior to Manjaro. Give it a whirl if you haven’t yet.
