If it works for you -- go for it. both "works". For todays trend of solving everything by more hardware ZFS may even have "enough" performance. But still it is dangerous for a reasons i explained, as well as it promotes bad setups and layouts like making single filesystem out of large amount of disks. This is bad for no matter what filesystem and RAID setup you use, or even what OS.
