It's funny, for me it's the opposite - logging with systemd is sooo much better
than with Upstart. (IIRC, the logging of stderr of Upstart jobs was a
NixOS-specific hack, and other than that there was no logging support.)

However, there is a long-standing issue with stdout/stderr logging: if the
process dies before systemd has had a change to process its log message, then
systemd may not be able to figure out the unit corresponding to the message, so
it may be lost (or not attributed to the unit). See

Also note that the journal has rate-limiting that may cause messages to be dropped.
