Depends. Slower desktop machines XFS.
Standard desktop XFS, if it has a smaller SSD, Btrfs.
Home server ext4/XFS + ZFS. Generic servers at work ext4/XFS, backup/storage servers ZFS.
Database server, experiment with ZFS with compression enabled - ratio 2:1, but encountered problems (probably a bad HBA model), standard ext4/XFS.
Hosts with virtualization, small server - XFS, big server - ZFS (technically a ZVOL).
Linux
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.

Servers - btrfs. Fewer layers of abstraction, easier to manipulate.
Laptops - ext4. I don't do anything weird with the onboard storage, plus it supports fscrypt.
Flash drives - exFAT. I usually need to access them on multiple platforms and exFAT is about as cross-platform as VFAT (but supports bigger files).
NTFS Usally for windows,ext4 for linux,btrfs to install linux on,vfat/fat32 for cross platform compatibility
ZFS for my server’s root pool and main storage pool. Ext4 with snapraid for my media pool. Currently btrfs on my desktop and ext4 under vanillaos on my laptop (not sure if I could partition it manually to use btrfs but I’m considering that for snapshots)
Most of my drives are EXT4, but I started using BTRFS a couple years ago and will be using it on all new installs from now on. I really like being able to make snapshots and compression reduces the install size quite a bit.
ext4 because I value my data and don't want to lose it. I used to mess about with ZFS for mass storage but it's a university course to learn how to use and have decent performance.
I used to use XFS, but ext4 caught up.
And I used to use XFS... on something other than Linux.
- Ext4 main computer
- NTFS for hard drives and stuff that need to be shared with other people using Windows
- BTRFS for the NAS
Every photocopy machine I've come across that accept USB sticks do not support exFAT, so what I would do with my USB stick is to split it into two partitions, one FAT32 and the rest exFAT.
Depends on the device and the use case, mostly FAT32, exFAT, NTFS, EXT4
