Btrfs has pretty much the same features listed above minus the cache drive handling. (You can still get the cache drive behaviour over bcache device) The raid has different modes, so you'll have to decide if what's available is enough for you.
None of the options are marked experimental. (Specific features are marked unstable on the status page)
"Under heavy development" does not mean anything about stability. The kernel itself is under heavy development. ZoL is under heavy development. The disk format is stable, which is what matters.
SUSE provides commercial support for btrfs and uses it as the default. That's pretty much as non-experimental as is gets.
In the past, when data integrity issues emerged, btrfs devs have stated that it is not ready for production. Has there been an announcement to the contrary? If btrfs is production ready, is this clearly stated somewhere? Solaris has defaulted to ZFS at least since version 11 first released eight years ago.
Update - also it appears Suse enterprise uses btrfs for the root os filesystem but xfs for everything else including by default /home. To me, this seems telling? If it’s so solid why not use it for /home?
