As for performance, I dont really care. I do suspect that BTRFS gets faster than ZFS when it is done. As a research paper explained: to get data safety you need to trade cpu performance and do lots of calculations on checksums. That is one of the reasons ext3 are faster than ZFS - they dont do as many checksum calculations as ZFS. That is also one of the reasons ZFS is much safer. I dont care about speed. If BTRFS is faster - congratulations.
