I was never a fan of Sampletron emulations but I like IK's version.
Syntronik - I wonder if developers will ever figure out making bloated synth emulations is a bad idea. Sire it my attract analog junkies nut there average humandoesn't want to use up large junks of space on a SSD drive for such things.
IK seems to be good at physical modeling. They should have tried that instead of competing with Soundpaint for the all time bloatness trophy.
You don't hear them in a mix with other stuff. If you rely on presets and do dance genres you will most like find something that works using Spire, Sylenth and Serum long before most of the AAS synths,
