Played around with it last night and it definitely sounds very different from any of NI's Vintage Organs or B4.
The real Hammond players here can describe it better, but I will say it has its own personality and it certainly isn't very smooth, pedestrian, clean or perfect. And, aside from being a Hammond, it doesn't sound very much like the others (even if you change B4's tonewheel settings).
And Worra, you might want to take a look - when loading, it's looking for "C:\Users\Worra\Desktop\..." and I have to tell it where I have it installed. Not a big deal, but just so you know.
