I still have a Yamaha SY77 with AFM and onboard FX as well as a TX802 rackmount module so FM is still a firm favorite of mine. The AFM on the SY77 adds even more capability to FM as on the DX7 and is capable of some great sounds.
I still don't find that many other synths have the range of dynamic velocity response that Yamaha's FM synths provide. They set a standard years ago that is hard to beat today. It is great to see Yamaha continue providing FM synthesis in their recent products.
