Cannot rate all of them, but I did listen to HFI-780, Momentum and AKG K702 (Not Anniversary ed though). I'd say HFI780 are better than others, and Momentum are probably the second, however they are quite different, so it really depends on your taste.
I didn't hear HD598, but did own HD595 for a long time and I'd prefer HD595 to any of the ones I mentioned above in terms of SQ.
Comfort-wise Momentums are #1.
Hope that helps
It is hard to rank them without knowing your musical preferences or what you are looking for in a headphone. For instance, if I was ranking on neutrality I would put the AKG K702's at number one, but if ranking for bass-impact I would put the PRO 750's at the top.
I listen to mainly Jazz and Indie-rock so my preference is for mid-centric headphones like the HD598 or the Momentum.
