ZFS is worse because ZFS in general only has one failure recovery method: restore from tape.
Most other mainstream filesystems have tools to restore and attempt at repair the filesystem meaning that you can often restore the data.
ZFS also utilizes the memory more which means that it is more likely to be affected by memory issues.
Is it likely? No. But since us mortals seldom have tape backups and usually can't afford to backup everything on their NAS I'd say that ECC is recommended for ZFS, more so than most other filesystems. Just as a consequence of how it is used and the lack of recovery tools, not because of the filesystem itself.
