I demoed both units, as well as the Elite 54tx when I was looking for a new AVR. Both of the above mentioned AVR's are very good and will do the job. I guess I would look at the options and try to find the one that has what your needing. You really don't say what comparisons your asking about, technical, sound, etc...? Some people say the Yammy's have a warmer sound and the Denon is brighter sounding. Everyone hears differently. I ended up getting Denon as the folks at Axiom said they are a good match for my m60's. Also, if your going to be driving 4ohm speakers, like the m80's, I have heard the Denon's will have no problems, not sure about the Yammy's.
