Though I consider zfs to be nice, I'm willing to use it only with distributions, where it comes with the distribution, built for the distro kernel (i.e. ubuntu or proxmox). In the past, I've wasted too much time with dkms, failing to build the kernel modules, or kABI modules failing to load, or other problems that left me without root filesystem at reboot. That's not an experience I'd like to repeat. Also, btrfs is nice too ;).
Regardless, I'm surprised your one-year with ZFS didn't convinced you that it's worthwhile to invest in its mastery. The filesystem will pay dividends for your entire compute life-time and not only save your data but hours of maintenance over that time.
Major downgrade moving away from it in my view.
On a side note, FreeBSD is great and worth investing in as well. I still have more to learn but the journey has been wonderful and I will not be using Linux in the next iteration of my home / lab server and hobby projects.
For example, I had to move between SSDs which is an absolutely trivial operation with any other filesystem if you know your Linux well. It took me maybe three hours of work on ZFS because it brings its own environment and does everything its own way, so I had to remember and re-discover a lot of stuff. The system booted on maybe 15th try.
If you are fine with this, or you're not going to use it on root, or you are a FreeBSD user, it's an excellent choice for pretty much any task.
