Hurd is still stuck using Mach, unfortunately. The issues from the Hurd critique paper haven't been addressed either.
Minix, as cool as it is, does not have a maintainer, and hasn't seen activity for years. There's a lot of out-of-tree work that's just sitting there. It is a shame, because it is a really cool system architecture.
Genode is a modern, proper multiserver OS that has a good architecture, frequent releases and quite solid overall direction. And it has POSIX compatibility, so a lot of software runs, including modern web browser engines.
Why Genode over Hurd and Minix considering those are also Unix-like same as QNX (which still exists btw)?
