Is it worth switching to BTRFS for the average user?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Transparent compression, snapshots, copy-on-write, deduplication, and data checksumming (and healing via read or scrub) are the main things you might notice as an end-user. BTRFS is mostly on par or slightly slower than other simpler filesystems for speed (can be faster on HDDs due to compression), so if you're using it you probably want to be taking advantage of the features it offers, not because it's going to be faster.
Healing won't work without copies (RAID) available. However, scrubbing regularly can also allow your drive to detect and correct errors before they become irreparable.
