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.

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 on PC, ZFS on my server and APFS on my mac
I've got Btrfs on my desktop for the OS drive cuz that was what Fedora recommended when I was installing it. It took a bit of effort to get snapshots working properly, but other than that, I've had no issues with it at all over the past year. I've got an exFAT drive and an NTFS drive in there that are kind of leftovers from using Windows. I've been thinking about reformatting the exFAT drive to ext4 or something, since all it really does is store games, and having the ability to symlink to it would be nice.
I've got a TrueNAS machine as well and that uses ZFS for pretty much everything.
Random thoughts, no particular order
I think btrfs was the default the last time I installed Bazzite, but I don't really know anything about it so I switched it to ext4. I understand the snapshot ability is nice with rolling release distros, though.
It'd been ages since I'd used FAT32 for anything until I made a Debian live USB when I was setting up my pi-hole on an old Core2Duo recently. It would only boot on FAT32 for reasons I probably once knew. 😆
NTFS was an improvement over the FATs what with the journaling, security, file streams, etc. I use it wherever I still use Windows (work).
Most of my general purpose USB flash drives use exFAT. I like not having to worry about eject/unmount.
NTFS feels rock solid if you use only Windows and extremely janky if you dual-boot. Linux currently can't really fix NTFS volumes and thus won't mount them if they're inconsistent.
As it happens, they're inconsistent all the time. I've had an NTFS volume become dirty after booting into Windows and then shutting down. Not a problem for Windows but Linux wouldn't touch the volume until I'd booted into Windows at least once.
I finally decided to use a storage upgrade to move most drives to Btrfs save for the Windows system volume and a shared data partition that's now on ExFAT because it's good enough for it.
By default, windows does "Fast Boot" which doesn't make booting any faster, but does have the benefit of leaving the volume in a mounted state when you shut it down.
Oh, right. Fast Boot. I forgot about that bundle of joy.
But that's wasn't the only instance of an NTFS volume suddenly being broken. Another favorite was when I shrunk a volume on one disk from Linux (and then remembered that Windows correspond done it better) and rebooted to have it fixed and Windows proceeded to repair one on a different disk.

My regular computer is ext4.
I assume my raspberry pi is ext4, but I've never checked what DietPi runs as default. It works fine.
My 720xd is ext4 on the OS drives, but the storage drives are ZFS with dual parity.
I wish I'd actually chosen a file system instead of just letting window's at the time default to NTFS for external drives.
Moving from Windows to Debian; NTFS has been nothing but a headache. I've actually had to setup a windows machine to serve that drive pool via SAMBA as Linux just won't play nicely with it.
