While it is tempting to descend into bashing on a list with mostly favorable posters, I will try to maintain as much as objectivity as I can. ReFS, from the limited information that is available, roughly corresponds to ZFS's SPA and lower layers. As such, it inherits the upper NTFS layers with support for file compression, encryption, sparse files, links, quotas, etc. This approach is interesting, but at as it stands at the moment, ReFS has quite a long way to go before it can be said to approach ZFS in terms of feature-completeness. To my knowledge, parity RAID support is very limited and there's no support for any kind of tiered storage, dedup, writable-snapshots, layered filesystem objects, volume objects, booting off of ReFS volumes, etc. Another important fact is that ReFS is new. Filesystems are extremely complex codebases which require very a careful approach, or "Bad Things(tm)" happen (i.e. data loss), so admins tend to be very careful in trying out new stuff in production. Lastly, ZFS has tons of runtime experience behind it, lots of knowledge in the community on how to tune it and how to handle problems. Over time, this will be built for ReFS, but it is a slow and painstaking process (aptly described by Bryan Cantrill as "walking the trail of tears").
