Depends what you are looking for? NC or SQ? I wanted a good balance of both so I went for PXC-550.
You can also add in Sony's MDR-1000X to your list.

Got it from Amazon. The NC for PCX-550 is much better than the Momentum but still just below the QC35.
Sound wise PXC-550 is a better all rounder, as in I got it specifically for both music and movies since I'll be using it on flights. And being able to turn off the NC in Bluetooth mode is a big plus.
One big drawback I noticed so far is i can't sleep tilted with the headphone cups putting pressure on the pillow as it affects the NC. That means sleeping facing straight or heads down which is very annoying.
Not sure if the QC35 has the same problem, interested to find out.

I think you can test the MDR-1000X in Sony Centres in KLCC/Curve as they are having a showcase event. You can check the other thread for the dates.
