Solaris used to be far ahead compared to Linux. It's not really the case anymore. > coughbtrfscoughsystemtapcoughsystemdcoughepoll Btrfs is not as mature but design wise it is competitive with ZFS. Pool resizing is actually a lot nicer in Btrfs. SystemTap was not as good as Dtrace but Bpftrace is ihmo better than both. Event ports remain better than epoll but as a user that's not particularly significant. Systemd is ihmo better than SMF was. The combination of Linux namespaces and cgroup allow you to do everything zones can but are more flexible.

I'm not a huge ZFS fan but I think ZFS-on-Linux more or less spells the death of BtrFS. BtrFS has been radically unfinished and unready for over a decade now; meanwhile ZFS is decades old and in-production for much of that time. Does anyone use BtrFS in production? To the best of my knowledge, the answer is no. (To be clear, I don't think Solaris is the best platform to run ZFS today.)

Oh, and ZFS is full of bugs as well, it's far from done and being actively fixed and improved by ZoL people, that's why freebsd people are switching to ZoL. I've never heard much arguments why ZFS is better than Btrfs, I would like to hear some (safe for RAID6).

illumos split from Solaris around the time Solaris 11 has been released. Since then the development of both mostly diverge. Unlike others I think that Solaris is still being developed but not so obviously. Partly because it is limited to paying customers (non-paying customers can only access official releases like 11.1, 11.2, 11.3 and so on. And this happens seldomly) and most changes happen in not so obvious parts (eg. low level tools and protocols). BTW: From its Solaris inheritance illumos got a lot of technologies despite the always mentioned SMF, ZFS, Crossbow and DTrace. Eg. authorizations, privileges and roles. Things that I miss when I look at other OS's. Many valuable things are hidden below the surface. Between Linux and illumos there is a big difference between their development philosophies. For me Linux takes now the part of Windows two decades ago: It is heading towards a monoculture with masses of lemmings running with it mostly ignoring superior technology around.
