I had the same experience. Nano is great if you’re used to notepad or a generic, limited text editor.

Once you learn a terminal editor like eMacs or vim, why go back? So much less hand motion going to mouse, arrows, and back.

Wait til your table with all the checksums gets messed up on an “older” btrfs install. Happened to me on a VM because I didn’t know copy-on-write should be disabled for large frequently partially updated files. It also slowed that VMs IO down a lot.

Like most file systems, BTRFS is great if you know the edge cases. I recently moved to ZFS on my new work system, which has been a great change in terms of in-line snapshots and the like.

If EXT4 meets your needs, that’s awesome. If you understand how to use a different FS well or are willing to learn (and risk), I would also encourage other options as well.
