It is a very interesting topic, Tracknet. And not much usual here.

I can't give a honest opinion, because I don't know different brand styles too much.
I only may say that (for my ears) Yamaha styles are the more usable ones, but not specially inspiring (too much simple ones).

Perhaps Synthzone members which know well different brands, or have a keyboard store, may give an opinion: Fran Carango, George Kaye, Dreamer, Dan, Don Mason...

I would like to read their opinions about this interesting topic.
