I also agree that there probably at this point of time should be more zfs tools written for the few situations that do happen when things get broken. Although I still standby my opinion I consider ZFS a huge amount more robust than UFS, UFS always felt like I only had to sneeze the wrong way and I would get issues. There was even one occasion simply installing the OS on its defaults, gave me corrupted data on UFS (9.0 release had nasty UFS journalling bug which corrupted data without any power cuts etc.). In future I suggest you use mirror if the data matters. I know it costs more in capacity for redundancy but in todays era of large drives its the only real sensible option. On the drive failures you have clearly been quite unlucky, and the other stuff is unusual.
