Unfortunately, I own Blue3, VB3, B-5, NI Vintage Organs, and several Kontakt Samples. lol I haven’t bought the IK Multimedia version yet, but I know some people who think it is not good and I know several people, you love it.
I just bought a Kurzweil PC2R and those organs sound pretty good. I am going to purchase the Hammond XK-5 over the next several months and I have played that and it sounds wonderful. I know a few people who own them and still swear by using the Ventilator II with it.
So, yes it is all subjective.
