ZFS ONE Pool vs. xfs multiple pools for different purposes

[takkkkkkk]

My current unraid has multiple xfs pooled devices for different purposes. For example, I have 1 devices dedicated to hosting plex meta data, another for incomplete download, cache, VM, etc. 

with integration of zfs in the new unraid version, I'm thinking if I should overhaul and convert them into one multi-purpose ZFS pool. 

Is there any "cons" of doing it? Last time I tried one multi-functioning pooled drives with BTRFS, it was constantly getting locked because the pool was being leveraged by other functions (usenet unpack/download cache, etc)

Any thoughts?

ZFS is best (I invite alternatives).

I only have one XFS array in UnRaid and maybe I'm not the best person to give advice.
