Easier to work with, yes, but a RAIDz2 will statistically be safer than a set of mirrors, since in many cases, you loose a drive and during resilver, you find bad sectors on another drive in the same VDEV, resulting in data corruption. With RAIDz2 (or 3), the chance of these errors to be on the same place on all drives is quite minimal. With a (striped?) mirror, a single bitflip on the 'healthy' drive will involve data corruption.
