I will say, if you're a newbie, then btrfs has one big benefit, especially when combined with Grub or Limine as your boot loader, and that is the ability to just roll back to a previous snapshot when something breaks.
Playing with things and breaking things as you learn is a lot less of a hassle when you can simply roll back your system to where it was yesterday, instead of having to re-install it from scratch
No no no. That won't work with btrfs snapshots if you've had a kernel upgrade. Choose grub from those two
