The init system used a series of hard-coded numbers in the init scripts 
to judge which services were to be started in which sequence, which was 
a horrible mess.

You had to make sure the service X's priority of 37 was in between 
service Y'x priority of 18 and service Z's priority of 56.

With systemd, you just say things like:

After=syslog.target network.target auditd.service
and/or
Before=poweroff.service reboot.service halt.service

Which is MUCH more concise and easy to understand. The computer figures 
it all out, instead of the user having to juggle priority levels.

Also, all init scripts with priorities > 37 would all have to wait for 
the "service X" to finish. This is not so with systemd. The service 
files specify the minimum dependencies. If service Z does not require 
service X, it can go ahead, even if service X gets delayed.

See?
