While there may be some possible optimizations, i'm sure everyone would love the random performance of mirror vdevs, combined with the redundancy of raidz3 and the space of a raidz1. However, as in all systems, there are tradeoffs.
In my opinion periodic scrubs are most useful for pools based on mirrors, or raidz1, and much less useful for pools based on raidz2 or raidz3. It is useful to run a scrub at least once on a well-populated new pool in order to validate the hardware and OS, but otherwise, the scrub is most useful for discovering bit-rot in singly-redundant pools.
