I'm an FM junkie and own various pieces of gear based on old yamaha FM chips, as well as actual yamaha FM keyboards. I think the various emulations out there are actually pretty good, and I have to admit I'd probably have a tough time with blind A/B tests. Probably the most noticeable (and sought after) out of the "lo-fi" effects is the ladder distortion effect on the old Sega megadrive YM2612 chips. I own a MegaFM synth with one of those and I do love the sound. I'm not sure if most emulators actually try to emulate it, but the plogue chipsynth MD plugin does.
