I honestly can't see your point as it equates the quality of the artist's work with the hardware.
I agree that this is an unfair view; nevertheless, it's the kind of unfair view humans are given to, frequently without even realizing it, because we tend to apply negative associations to pretty much anything involved in a negative experience, however indirectly. It's the same sort of logic that led to me thinking I just didn't like beer for about five years when all I'd had was Anheiser-Busch crap. A sensible conclusion? Not remotely, as I discovered later; nonetheless, kind of an understandable one.
And those previous examples of Adlib sound are a sterling example of how much better Yamaha sound generation is than that used in the C64 or the Amiga.
They're good examples of what even simple 2-op FM can do when used well, to be sure; however, arguing that FM is just unequivocally altogether better than other hardware is a little more difficult to support. The OPL2 has the advantage in terms of polyphony, certainly, and is capable of some lovely highs - but the Amiga is capable of a vastly broader range of timbres, and the SID, limited as it is, has (for most people, though I gather not for yourself) an extremely pleasing quality when used well.
