Running btrfs in production is still a nightmare in 2017. At least the random kernel crashes stopped. With proper care and feeding, it won't run out of metadata either but you need to monitor it closely and run nightly balances. Which probably kill your SSD. Documentation sucks. Get used to monitor the btrfs IRC channel closely and deduce what to do and what not to do on which kernel version. It works well for very particular use cases (file server with few random writes and much duplicate data). Cannot recommend it otherwise. Even Docker runs more stable on XFS.
