My gut feeling is no. I wouldn't put it on mission critical stuff yet. Its
not that I have had any major bad experiences (x fingers) but im not aware
of any major deployments of it in the wild. As a result I wouldnt feel safe

What I would advise is to think carefully about what you actually need. If
you dont really need zfs features, then fine go with ufs, as you can always
migrate in the future. However if the features are useful to you and of
enough of a benefit to justify I would advise going for a Solaris platform
of some kind.
If you are doing it on a budget, go for openindiana, but if you have a some
budget, go for the safe option of solaris 10 u9.
It all really depends on your particular circumstances.
A few tips
put the os on its own zpool and the data on its own. That way its fairly
easy to migrate to another os in the future.
go big on ram, the more the better
go for more cores rather than core speed, as zfs will benefit a lot from
more threads (it was designed to run on coolthread archs which have 128+
virt cpus). Also enable hyperthreading if on intel
look at using ssd for l2arc if you need performance, or are using dedup
