I have found that the Orange and Cyan finish nearly the same for myself. They are very different (in terms of cell structure) foams. I don't personally like the feel of Cyan pads in larger sizes (6.5 and above) nor do I like them on a rotary. For a cutting pad they are great (to me) in 5.5 or 4 inch sizes.
I don't think the orange have more potential for marring then the Cyan (I would say it is about equal in my experience).
