xfs has had large file and large filesystem support for ages, so it is well-tested in that regard. ext4 can do larger filesystems now, but is still limited to 16TB files. zfs ist comparable to xfs in that regard.
xfs integrates well into linux and has had excellent performance. zfs is rather odd as a filesystem and circumvents several common linux mechanisms, making it rather awkward. You need to special case everything for zfs in monitoring (sizes are hierarchical overlapping instead of exclusive), ACL support and admin tooling (volume management and partitioning is completely different for zfs, trim is weird, booting is weird). zfs performance is also lacking due to it being very odd and special-casey in the linux kernel, as well as RAM-hungry.
