Fair enough. I can only refer to my own bad experiences.

I used openSUSE every day for 4 and a bit years on 2 or 3 machines. I
had a disk crash with fatal, unfixable disk corruption at least once
per year.

(I am very very glad I used a separate, dedicated home partition,
usually partitioned XFS, so I did not lose any data, but frequent
reinstalls were part of life with openSUSE.)

I am very underwhelmed by Btrfs, and would not trust it on any machine
without a UPS.

It's not just me:

SUSE's own advice:

NOTE:

«
WARNING: Using '--repair' can further damage a filesystem instead of
helping if it can't fix your particular issue.

Also note the warning here:

LVM adds pointless complexity I've never needed. The only time I've
needed to enable it was to enable LUKS.

Then, I discovered you can't edit, change or resize encrypted
partitions. It took me about _three days_ to get a successful Fedora
install on an encrypted disk, with reasonably-sized volumes, and the
performance felt more like a HDD than the fast SSD it was.

I have had more data loss with Btrfs in ~4Y than in about 25Y using ext2/3/4.

ReiserFS was over when he went to jail for murdering his wife, and I
would have recommended anyone and everyone to abandon it forthwith
then.

Snap works. It does slow boot a bit, but it's easy and safe. I use it
for Skype, for example.

Flatpak works. I use it for Slack, Zoom, Spotify, and a few other
proprietary nonfree tools.

Both are hideously space-inefficient. Both have issues with dependency
management; I use a script from Alan Pope for cleaning up old snaps,
but *I shouldn't have to*.

Both have inadequate CLIs IMHO. Both prompt me when doing updates, for
example, and neither understands "-y" which I feel should mean "just
bl**dy get on with it and stop asking me stupid questions!"

But they are easier than adding external repos for proprietary stuff
and hoping the 3rd party maintains their packages.
