In my (personal) opinion, DM Evo are have a very modern, ice-pick trebly and cold tone. I owned them a long time ago, in a different setup... The only thing I was loving about them was the incredible pinch harmonics I can get with them. Anyway, a direct comparison with RY would be difficult.
I would say the RY are more organic, less modern, cutting tone without being harsh. Less "extreme", more versatile.
