Is rsync faster? As I have understood it, "zfs send.." gives me an

It is true that rsync (as of 3.0.5, anyway) does not preserve NFSv4/
ZFS
ACL's. It also cannot handle ZFS snapshots.
On the other hand, you can run multiple rsync's in parallel; You can
only do that with zfs send/recv if you have multiple, independent ZFS
datasets that can be done in parallel. So which one goes faster will
depend on your situation.
Yes. Your configuration and intended use impacts the decision.
Also, b119 improves stat() performance, which should help rsync
and other file-based backup software.
