ESPECIALLY in 8.0,1,2 versions. Do you have significant, long-term experience with "random crashes and lots of missing data"? I have nothing but good things to say about ZFS. I've been using it since 7.0, and one box in particular is put under extreme duress doing network backups daily. Since originally tuned, it has been just as stable as any other box we own. This particular box is configured as Tim's is in another post he wrote (7.2, RAIDZ, boot from UFS flash), and writes at ~160MBps for 6-8 consecutive hours per day. What I would recommend is if you go with -CURRENT and boot from ZFS on a box going into production, ensure that you have very up-to-date backups, stored in a method in which you could very quickly replicate onto another box in case of emergency.
