Not sure about boot speed. At least on my system booting Debian became noticably slower in Debian 8,9 and again in 10. Maybe simply because software got larger or because I didn't do clean installs but upgraded my existing system, I don't know. But the only boot speed improvement I got in the last years was switching to SSD. Thought I do like that with systemd you can at least find out easier which parts slow down the boot process.
