Binary logs with checksums is one benefit, much harder for a hacker or 
malware to hide its tracks.

Binary logging also makes it easier / faster to look at specific types 
of events in the log.

And sockets can be used before the service is actually started, so 
services that want to log for example can start before the logger is 
finished coming up.

And it allows services to start on demand and stop when no longer 
needed. I don't use that, but that is not as easy to do with system V init.

It also reduces issues related to poorly scripted init scripts, and 
needing to sometimes change the numbers to make sure services start in 
the correct order.

There are benefits, at least to some people. And there isn't anything I 
could do with System V that can't be accomplished with systemd.

systemd isn't critical to use, not for me, but other than needing to do 
a little research and learning, it also isn't a negative.
