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.

ext4 certainly has its place, it's a fine default file system, there's really no problems with it.
But others, like ZFS and BTRFS, have features that you may want to use, but ext4 doesn't do: fs snapshots, data compression, built in encryption (to a degree, usually only happening for data and some of the metadata, so LUKS is often better IMHO), checking for bitrot and restoring it when possible (whether it is depends on your config), quotas per user group or project, spanning multiple disks like with RAID but safer (to a degree), and others.
