I work with systemd on Gentoo, but it was certainly not easy to get it all working.
First I had problems with wicd, after that was solved I had still no sound as user, only as root...
After lots of searching on forums, howto's etc... I got finally pulseaudio working properly.
Then there were issues with sound on firefox, and that could be resolved by adding/creating asound.conf to /etc witch should not be necessary when reading the how-to on Gentoo...
Finally on the end, everything is working, and indeed: systemd boots much faster than with init scripts.
You have to re-learn a lot about the booting process, but on the end I found it worth the trouble.
Of course: rcinit is good and clear; when you're happy with it, stay there! I would never say people have to try out, but:
Big changes generate by many people aversion. Think back to the first start of kde4... or when HAL was replaced... or when grub2 came... etc,etc, etc...
