For example: I do not know any analog synth which sounds like my mwXT, unless the mw1 which sounds partially better, just not in all aspects of sounds you would like to create with it, UI is bad without access controller.
There is no analog synth I could swap for my Polymorph, it has its own sound.
With the Supernova2 I can do FM sounds with 8 operators, no analog counterpart for this, its sound is like velvet or silk through a germanium eq, but without it sounds stellar anyway.
And by this way I could list every synth I love to play with, which is any kind of VA.
We should not forget that analog synthesis is also only virtual analog, since its basic determination is to imitate: ocean waves, wind, birds, gunfire, thunder, rain and then to imitate acoustic instruments like violins, horns, brassd, drums, and so on.
Also what Audioharder said is one aspect that gets too often undermined: the OSC part of any given synthesizer, be it VA or not, is the main source or fountain of what we hear, even after filtering, as in subtractive synthesis, its the main role which “makes” the noise/sound we hear.
