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.

For me, BTRFS is worth it for the transparent compression and file integrity checks alone.
I am not sure what Fedora does for virtual machines via boxes (like transparently disabling COW), but one caveat with BTRFS is that you have to be aware that COW is a problem for usage patterns of virtual machines on their images. Just for this one example alone BTRFS is probably not a good fit for the average user.
Another thing which I just learned very recently, is to mount BTRFS volumes with the noatime option significantly speeds up a lot of workloads on my machine (machine has a decent SSD). Again, using the noatime option might create some problems in corner cases, so one should be aware what one is doing.
