Yamaha has some fantastic lead sounds. I found great guitars, new Pianos and Trumpets were good. Drums not as good to my ears as PA4X. I like organs on the 4x better, especially the way the lelie sim works. I'd say it is really close. I like the sound of both.
tried all the Presets and that sounded best to me, through Don's two Bose Compacts.
It seems to me they are leaving a lot of things to adjust by the user, but I suppose that's not all bad because it's easy to do.
I would have to change at least the volume on almost every OTS button.

Bear in mind that these are all minor things and can be readily and easily changed.
