I can only speak from my own limited experience, but for me ZFS on Ubuntu works as advertised. I was trying to put together a long term storage solution without becoming a storage expert. ZFS fit the bill. If you are nervous, go with a BSD: they are great choices.

I'll gladly take silent data corruption over a hard total failure of the entire volume any day. At least I have a chance at fixing the former, and for my use cases that's preferable.
Every time ZFS on linux is brought up it's always met with skepticism, just as a lot of people trying out ZFS in virtual machines discovered the hard way (lost volumes) there are a lot that can go wrong (and it does seem like it can go wrong) and any version running on linux will not have been tested as much making it a risk. And that's the thing you are trying to minimize with using ZFS on Linux in the first place...
Now BTRFS isn't ready for production yet so that leaves, well, nothing if you want checksums and cheap snapshots.
I guess I'll have to wait another 5 years and see if BTRFS is ready, until then it seems the only thing I can hope for is luck.
