I feel similarly. I've had basically all my data on ZFS/ZoL for 8 years at this point and have not had any problems except occasional system lockups when scrubbing. This has not happened for the last year or so. For a while it seemed like ZoL was working hard to catch up with the "official" ZFS feature set, but at this point I hope they take it slowly and carefully and really beat on new upgrades. The more stable you are, the more important it becomes for a FS to not screw it up, since the consequences get larger with a larger user base...
