Blue3 v. B4II

My favorite organ is Acoustic Samples B5 v2. The Leslie is superb, as is the vibrato/chorus. Blue 3 is excellent, too. The various organ models load instantly, unlike B5 v2, which take a few seconds. I like the fact that Spin can be used independently. I downloaded the VB3II demo, but have not spent enough time with it to form an opinion. I haven’t tried IK Multimedia’s Leslie yet, but so far the B5 v2 Leslie sounds the most authentic to my ears. Any suggestions on other rotary speaker options?
