My Arch Linux systems seem to boot much faster since they moved to systemd. I will admit I was pretty much lost when first working with it but I chalked that up to unfamiliarity and haven't had to touch it much since. Then again, I'm using a Debian 7 install right now and it boots quite fast and does not use systemd.
