About a year ago I switched to ZFS for Proxmox so that I wouldn't be running technology preview.

Btrfs gave me no issues for years and I even replaced a dying disk with no issues. I use raid 1 for my Proxmox machines. Anyway I moved to ZFS and it has been a less that ideal experience. The separate kernel modules mean that I can't downgrade the kernel plus the performance on my hardware is abysmal. I get only like 50-100mb/s vs the several hundred I would get with btrfs.

Any reason I shouldn't go back to btrfs? There seems to be a community fear of btrfs eating data or having unexplainable errors. That is sad to hear as btrfs has had lots of time to mature in the last 8 years. I would never have considered it 5-6 years ago but now it seems like a solid choice.

Anyone else pondering or using btrfs? It seems like a solid choice.

I doubt that. Some options:

  • bad memory
  • failing drives
  • silent CPU faults
  • poor power delivery

The list is endless. Maybe BTRFS is more tolerant of the problems you're facing, but that doesn't mean the problems are specific to ZFS. I recommend doing a bit of testing to see if everything looks fine on the HW side of things (memtest, smart tests, etc).
