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.

I used to associate btrfs with the word unreliable for years based on what I've read here and there, while ext4 appears to be rock solid. Pointing to sources for this is not easy though. Here's a start.
See Features and Caveats here for Btrfs : https://wiki.gentoo.org/wiki/Btrfs#Features
For Ext4 https://wiki.gentoo.org/wiki/Ext4
The "Caveats" section for BTRFS is trash, it is all about a ENOSPC issue that requires you to low level mess with the thing or run the fs for years over constant writes without any kind maintenance (with automatic defragmentation explicitly disabled). Frankly I can point from the top of my head real issues they aren't speaking about: RAID56 (everything?), RAID10 (improve reading performance with more parallelization).
If we take subvolumes, snapshots, deduplication, CoW, checksums and compression in consideration then there's no reason to ever use ext4 as it is just... archaic. Synology is pushing for BRTFS at home and business so they must have analytics backing that as well.
