I think we are lucky that each company has a different approach to sound...choice is a very good thing to have.
Back in the early days, it was Moog, Sequential Circuits, Oberheim, ARP, Yamaha, Roland...each having it's own character.
There were those in one camp, those in another...things haven't changed much much like nowadays other than a few new names and a few that fell by the wayside.
You sold your BK-9 Deane? DonM has just acquired one, I believe.
