Niners CVA vs DW link

I have read a lot about the DW link and have even did a demo so I know how it rides. My question is how does it compare to the Niners CVA system? Pros and cons, how it rides, climbs, decends, goes through rock gardens, which is more plush etc...

Has anyone rode both extensively and could be as unbiased as possible?

Oh I ride in New England area and am a clyde if this helps.
