It depends on your use case.
See this post by one of the Debian and upstream sysvinit developers:

I'm not familiar with daemontools, I just know that it exists and what
it's for. If it's so wonderful why wasn't installed by default by any
distro? Or was process supervision never considered a plus except by
the systemd developers.
"*Text* logging": The Debian systemd default is to enable text logging
by having "ForwardToSyslog=yes" in "/etc/systemd/journal.conf" and
rsyslog installed. Since the Debian "/etc/systemd/journal.conf"
storage default is "Storage=auto", you can delete "/var/log/journal"
and the journald logs will be only stored on tmpfs in
"/run/log/journal". You can achieve the same result by changing
"Storage=auto" to "Storage=volatile". You can go further and set
"Storage=none" to avoid having any journald logs stored and have the
logs forwarded to rsyslog (if you haven't changed that the default
Debian systemd forward setting).
