I think you answered your own question :-)

In the olden days, before good SSB rigs were common, direct FSK was the 
best -- perhaps the only -- way to generate clean RTTY signals.

Modern radios like the K3 offer excellent carrier and opposite sideband 
suppression, so AFSK can generate signals every bit as good as FSK, at 
least on a practical basis.  I'm sure there will be some who will be 
aghast and strongly differ with this assertion, but the point is that 
using AFSK on the K3 for RTTY operation works very well.
