Styles like sounds are very personal and my order of preference is:
Now because I have placed the Yamaha last, does this make it a bad arranger, absolutely not, itís just that it doesnít give ME the impression that I am listening to a live band.
Does the Roland being at the top mean itís the best arranger, No, it just means that I find the styles to sound more real then the others.
You ears prefer Korg and Yamaha, however it doesnít make them any better then the others; itís just YOUR personal preference.
BTW in case you are interested, sound wise my personal preference is:
Again yours will probably be different. (However it still doesnít make one better then the other)
Live entertainment, Real Ale, Great Scenery, Great Beaches, why would anyone want to live anywhere else (IÔŅĹm definitely staying put).
