I use systemd and find it to be significantly faster boot-wise than Upstart and the sysv scripts. One doesn't do socket initialization and the other is a bunch of slow ass shell scripts. It doesn't matter if systemd is beefy if the actual task of starting services is lightning fast. Just for comparison, last year I was triple booting Debian Testing, Ubuntu 12.04, and Arch. I use KDE on all 3 (I do active development on KDE in the Arch one) and logged my boot times over 6 months. I misplaced those records but the effective boot times were around 15 seconds for Debian, 25 for Ubuntu, and 5 for Arch. Mainly because tasks in Ubuntu like NetworkManager or tmpfs mounting were taking 5 - 10 seconds and nothing else was running.
