Komatsu GD655-6

I've asked about Komatsu graders in the past, but all the machines have newer series out now.
So I wanted to ask again...has anyone run one of these new Komatsu's? Most of the talk I see is about Deere and Cat.
How would these compare? In the brochure pics, visibility looks good. And they come with an awesome standard warranty and service plan.
