I like to think that software updates are to correct known software issues/problems/bugs, whereas software upgrades are to introduce new features (which may themselves introduce new software issues/problems/bugs!). That's why I waited couple of weeks before installing Mojave - to see if anyone had reported any issues.
Having installed Mojave I have not knowingly used any of the new features as they seemed superfluous for me, I only did it because on those few occasions I contact Apple Support they generally like you to be running the latest software version for obvious reasons. Just my thoughts of course, I am not a software professional.
Edited to add. I've just performed a routine 'check I have the latest software on my iMac' procedure'. I am currently running 10.14.1, the iMac is telling me that an update is available for my iMac to run 10.14.2. I can't cutnpaste why the update is necessary as it won't let me, but it says that it will improve the stability of the software etc etc. So I would say this is an 'update' rather than an 'upgrade'.
