I used ZFS with DKMS on CentOS back in the day, and I found it a pain. It took a long time to compile, and I had some issues with upgrades as well (it's been a few years, so I have forgotten what the exact issues were).

When it comes to filesystems, I very much appreciate the "it just works" experience – not having a working filesystem is not having a working system and it a pain to solve.

Again, all of this has been a while. Maybe it's better now and I'm not opposed to trying, but I consider "having to use DKMS" to be a downside of ZFS.
