Had a problem on a NAS where BTRFS was taking "too long" for systemD to check it, so just didn't mount it... bit of config tweaking and all is well again.
I use EXT* and BTRFS where ever I can because I can manipulate it with standard tools (inc gparted).
I have 1 LVM system which was interesting, but I wouldn't do it that way in the future (used to add drives on a media PC)
And as for ZFS ... I'd say it's very similar to BTRFS, but just slightly too complex on Linux with all the licensing issues, etc. so I just can't be bothered with it.
As a throw-away comment, I'd say ZFS is used by TrusNAS (not a problem, just sayin'...) and... that's about it??
As to the OPs original question, I agree with the others here... something's not right there, but it's probably not the filesystem.
