ZFS vs BTRFS for SSD Cache pool

Hello Unraid community,

I recently bought two low budget 1TB Silicon Power SSDs for my cache pool (so i can mirror them) and without issues set them up as ZFS pool. Later on someone told me that ZFS is way more write intensive for SSDs than BTRFS, but I keep reading how BTRFS unstable is for a lot of people.

Now I'm stuck and not sure if I should switch my pool to BTRFS or keep it on ZFS. I don't want for my SSDs to get used up really quick.

SSDs will only hold docker containers and their data, of course I'm also backing up docker data on weekly basis so even if there is corruption of data I can restore it from backups.

Also server has i5 13500 with 32GB RAM so there should be no problems to run either ZFS or BTRFS.
