I run all 3 in various forms these days - Illumos, freebsd, ZoL - honestly ZoL is where I'm most excited about the future. I am seeing long standing stability/availability bugs finally getting fixed within the ZoL project - often times being fixes to OpenZFS upstream, fixing bugs that certainly "felt" like the same thing on those other platforms. There are zero platforms I entirely trust to survive every conceivable drive failure, I've had production outages using every combination of hardware and OS possible due to bugs both in the OpenZFS stack itself, as well as underlying OS issues on all platforms. At this point I think it's choose which OS you're most comfortable with, the ZFS bits are getting really close to on par. And there are many reasons to want to run a linux kernel with ZFS - not just "preference" related.
