Is that the only bad experience?
That's the main one. My motherboard got fried. So, I bought a new motherboard. I booted from ISO, and checked that the disk can be accessed and the filesystem is not damaged. All was OK. So, I tried to boot from it, but couldn't. Eventually, I booted from ISO, bind mount all the mount points, chroot, and reinstall boot loader. Second bad experience is moving from smaller disk to larger disk. With MBR, you just "dd", adjust the partition, and then the filesystem. With GPT, you can't do that, because GPT has secondary partition table at the end of disk. Nowdays, you use Clonezilla or GParted for that. OK, minor point.

I don't really understand everything about BTRFS. I understand it can partition the storage it manages, a bit like LVM.
I'm told it's more like ZFS (I haven't used ZFS). I use btrfs for backup/restore, because - It allows me to combine many non-identical disks into single "drive". I'm still using Samsung rotating hard disks which I paid good money for. - It can take snapshots, daily, weekly, and monthly. Snapshots are generally cheap.
