ext4, but the btrfs activity visible in the kernel changelog has slowed down recently after a long period of many bug fixes, so maybe I'll give it a try next time.

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).
I use Btrfs for my root partition to be able to rollback if something goes wrong after update. XFS: in all other cases, since I hate the lost+found directory on ext4. Although I don't think there's any significant difference between ext4 and xfs in performance and reliability.
Btrfs for the compression and snapshots
Depends on the device and the use case, mostly FAT32, exFAT, NTFS, EXT4
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.
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.
NTFS for the drive I had before jumping to Mint. Currently reporting several hundred gigabytes free, but refusing to make any new files, because... I don't know. I'll deal with it after an upcoming move.
The OS / home SSD is ext4, and so is the fat loud hard disk I recently purchased through an entire month of fighting Amazon over gift cards.
Btrfs on my Linux desktops and laptops, ZFS on my server, APFS on my Apple devices I guess
EXT4 on PC, ZFS on my server and APFS on my mac
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.
