I use f2fs on ssd's and ext4 on hdd's
I don't see the need for snapshots, I backup externally

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.

f2fs does one of the weirdest things with compression by default: the files are compressed but they still take up the same amount of blocks as the uncompressed files. This can get you the slight performance boost of compressed files, but doesn’t actually save you space which is an odd choice. You can enable a flag in the kernel but it has other effects as well.

I always go LVM + BTRFS these days. I simply love the versatility.
EDIT: DO NOT DO THIS LMAO, JUST USE BTRFS, I AM SO STUPID
I'm curious, why do you use LVM with BTRFS and not just use BTRFS built in subvolumes?
Because I'm stupid and like to run my partitions across multiple drives. 😅
Well since so many people recommend btrfs because "it have never lost any data for me". I want to suggest OP to never use btrfs ever. Because it has lost my data, at least three separate times, the most recent time a week ago. And it's not because of a power loss or anything, it just corrupted my files for absolutely no reason at all.
Stay away from btrfs at all costs.
"It's never lost data for me. Yet" is what they mean.
I totally agree, the only file system I've lost data with as a result of a file system corruption not caused by hardware errors or power problems in 35 years has been btrfs. FAT even served me better.
BTRFS for the OS partitions, ext4 for /home, tmpfs for /tmp. I rarely need to use snapshots, but I do use a rolling release. It's one of those things you don't need until you really fucking NEED it. Tumbleweed support is great - I can roll back a bad update in about as long as it takes to reboot.
This is exactly how and what Im using.
Home and other ext4 are backed up one form or another on by NAS.
Seeing that user Flatpaks are installed in the home folder, I see this as an interesting strategy. EXT4 still beats BTRFS in certain read/write benchmarks. My only problem being that you lose provisioning.
I don't see a lot of people talking about this here, but BTRFS subvolume provisioning is probably the best reason to use BTRFS - and BCacheFS - not just CoW or snapshotting.
The old way, of having a set beginning and end of a partition, is like caveman technology to me now. Subvolumes are here to stay and I am happy about that.
If I need to do a little distrohop now, even though I wouldn't (rpm-ostree rebase go brrrr), all I'd do is delete an recreate the "@" subvolume (or the root subvolume) without touching another partition or subvolume. All storage space is shared between subvolumes, basically, removing that boundary distinction between them, so I get to keep the files, permissions and meta data in my "@home" and my "@var" subvolumes, even though I get rid of the old "@" to replace it with a new one.
Therefore the idea of having storage that is reliant upon partitioning, ordering sectors one after another, having to defragment and keep strict separations between them is absolutely archaic to me. I'll gladly take a slight performance hit just for the convenience of avoiding all that.
I like btrfs but only cause it got transparent compression. I don't need the extra disk space and it only helps a bit but I just think it's neat
I used ext4 for yeeeeaaaarrssss but now I'm using LUKS+btrfs, stable, encrypted.
FS is for nubz, do these instead:
Read
dd if=/dev/sda of=/dev/stdout
Write
dd if=/dev/stdin of=/dev/sda
