Interesting idea. First, I collected lists of binary packages with
init.d files and systemd *.service files.

apt-file search etc/init.d/ | cut -d: -f1 | sort | uniq > init.d
apt-file search -x 'systemd/system/.+\.service' | cut -d: -f1 | sort | uniq > service

Next, counts of packages that have both

$ cat init.d service | sort | uniq -d | wc -l
774

and those that only have one or the other

$ cat init.d service | sort | uniq -u | wc -l
737

Figuring out how many only have init.d files

$ diff -U0 init.d service | grep -E '^-[^-]' | wc -l
302

and how many only have *.service files

$ diff -U0 init.d service | grep -E '^\+[^+]' | wc -l
435

If interested in which packages were counted, leave of the `| wc -l`
bit.

BTW, did you know that systemd ships 113 *.service files itself? And
that there are another 31 in systemd-* packages? And yet another five
more in *-systemd packages?

For comparison, initscripts "only" ships 25 init.d files.

Disclaimer: I haven't looked at the contents of any of these files.
Come to think of it, the init.d files include /etc/init.d/README :-P

Hope this helps,
