Hi,
As far as bugginess is concerned, I have never found Mac OS 8.5 to be particularly bad.
People have also complained about the initial release of OS 9 being buggy. Except for a mysterious "Preserve memory contents on sleep" checkbox in the energy control panel which seems to crash the machine if activated, I haven't experienced any bugs (and, of note to me, that checkbox is disabled in subsequent versions of OS 9).
In fact, I've found that every version I've tried (6.0.x, 7.0.x, 7.1.x, 7.5, 7.5.3, 7.5.5, 7.6, 8.1, 8.5, 8.6, 9.0, and so on) has been very stable.
Also, I've found that more recent versions (in particular 9.0 and up) are slightly easier to crash if I really want it to (probably a manifestation of the purported bugs in those releases).
