To each their own. I don't like that you can't do something simple like expanding a pool. You have to create a new pool and add that to an existing pool or something weird like that. ZFS can't beat hardware RAID on performance (when comparing something like 15K RPM SAS drives or SSDs), especially when newer controllers (LSI specifically) have features like CacheCade, adding in an SSD Cache in front of the array.
Adding a drive to a pool is a one click process with napp-it and only takes two lines in shell. ZFS SSD caching is supported via L2ARC/ZiL.
I think performance maybe better on ZFS specially since it leverages system RAM and benefits as L1 cache vs the tiny on board RAM on RAID cards. I haven't done formal benchmarks, though. ZFS SSD caching is supported via L2ARC/ZiL and it's native to the filesystem.
