There are still plenty of major bugs in Mojave despite the fact that we are already on the fifth iteration (10.14.4). The general concensus used to be to wait for the .2 to give Apple enough time to iron out the major kinks but now it seems that they not only don't fix existing bugs but also add new ones with each release.
Personally, I am not going to touch 10.14 ever again, and am also quite possibly going to stay away from 10.15 until High Sierra is no longer supported. None of Mojave's features are even remotely interesting to me, and I found myself kicked in the balls repeatedly by some of Apple's stupid design decisions. Like the one where they decided to move the file information in the right-most pane of the Finder to the bottom below the new Quick Actions that - surprise, surprise - cannot be disabled.
Basically, it's up to you. You might not be affected by any of the dealbreakers (multiple Gmail accounts no longer supported, external FileVault-encrypted drives no longer work, some external drives refuse to mount occasionally, iMacs tend to suffer from regular sleep-wake-failures, Quick Actions in the way, nonstop pop-ups from applications asking for access tp the most basic features of macOS because those now require individual permission, etc.) and might enjoy some of Mojave's features, like dark mode, quick actions or dynamic backgrounds.
