Looks like Ubuntu and Chrome are sticking with Upstart and even extending it. http://lwn.net/Articles/546963/
systemctl is just another thing I've gotten used to on Fedora. Its nowhere near as bad as NetworkManager which goes out of its way to interfere with your port configuration.
systemd is the 5th init system I've used. Upstart made a brief appearance in Fedora 9. Before that chkconfig, before that was /etc/inittab and way early was shell scripts rc.net, rc.local, etc.
systemd might be a little more complex but don't believe all of the bashing. Most of the criticisms are non-issues.
