I still use a Yamaha TX802 and SY77 with AFM. The SY77 also has onboard effects which adds a new dimension to the FM patches. FM patches can be very expressive to play responding dynamically to velocity unlike most other synths.

And Roland's LA synthesis was nothing like FM. Those synths mixed digital wave sample "partials" with an analog synth circuit. The waves were very small due to the cost of memory at the time. The Roland D50 provided many hit sounds on records.

FM is very unique and when run through effects is capable of great sounds. You either like FM or you don't I guess.
