I regularly use NIB4II, Gsi VB3, NI Vintage Organs (Kontakt), SounDUST Hammr+ (Kontakt), and now most recently I’ve added Retro Organs for UVI, and B5 for UVI workstation. Depending on the TYPE of B3 sound needed for a song, rarely does ONE or more of those options come short. They all specialize in very different areas if you learn the software for each.
I don’t use the original NI B4 just their second version.
I don’t use Arturia.
I don’t use VB-33
