As far as I'm concerned, while there are 'wow!' moments within an arranger in the odd style, performance or sound, none of them are just flat out perfect... for me!
And, to be honest, that makes me glad. I'm not exactly trying to sound the same as everybody else. I'm just looking for the easiest way to make any arranger mine. All of them nowadays are adequate. Most of them have all the editing tools you need to make an arranger shine. And ALL of them need you to use those editing tools! As far as I am concerned, they ALL need a lot of tweaking.
For starters, I'm the kind of player that wants to play as much of it myself as possible. Some arrangers' styles are too busy to leave enough room for me to do my thing. Great for those that want most of it done for them. But that's not me! Then I'm looking for something that convinces me there's a drummer next to me.
But as long as a FEW of the styles are outstanding, I know they ALL can be, with work! But the arranger where they all are hasn't been made, yet.
So, a lot of my decision making revolves around how easy it is to do the majority of tweaks. I know I'm going to be doing it a lot! John, I think a lot of the Roland stuff is individual. I doubt much of my stuff would be of use to you. And, to be honest, I worked long and hard to sound like this. Why do I want to make everybody else sound like me?
Even if they wanted to!
