Personally, judging an arranger a 'winner' based on just a few lead sounds is shallow in the extreme. I guarantee, for every good sound in one arranger, there are bad ones too. The only way you can judge something a 'winner' is to listen to the whole thing. That bass sound that sounded tubby when soloed might fit the mix perfectly. That nice, full and fat sax sound might swamp the mix unless EQ'd.
Then, everyone looks for something different in an arranger. I might want to be convinced I am sitting next to a real drummer. Someone else might want to think he is listening to a CD. Someone might want a thousand swing styles. Someone might only want three, but want a thousand disco styles. Weight might matter to one, and not another.
There ARE no winners and losers. Just arrangers that fit what WE want an arranger to do, or not...
An arranger is just a tool. What matters is what you build with it..!
