Yes, the thread has shifted a bit.
I would likely give the FA the edge over MODX/Krome, or Juno DS for VA synth... but for "realistic" sounds the only non-piano FA sounds that employ their more recent SuperNATURAL tech are EPs, clav, organ, basses, acoustic guitar, and ensemble strings. All the rest are from the XV-5080... and while, as I said "within reason, age doesn't tell you so much" I think you are getting to the edge of within reason as that 64 mb soundset is a full 20 years old. Not that there aren't tons of pleasing and useful sounds in it, but for most acoustic instrument emulations, I would be surprised if you could not generally find more realistic sounds in competitors with newer/ larger sound sets. Even the Juno DS, being based on later Fantoms, is probably a step up in realism from the 5080 set (though the Juno DS and FA share the same SRX-based Expansions, 2 of them in the FA, 1 of them in the DS).
