I was not referring to sounds primarily, but now that you mentioned it, except for organs the Korg does not sound better across the board....If you want to compare PCM samples, remove the excellent effects Korg uses from the patches..yuk.[pianos were the worst],yuk again..[In my opinion] ..BTW , I too owned the O1W/FD as well as the modules..I quickly moved on to other brands..When I played the Korgs , I always had a Roland next to it to bail it out...
