I think Jason hit the nail on the head....
It really depends on your head.
I was a fan of Lightspeed for many years and had purchased four headsets previously. I found flying with Zulu's in a friends RV, that whenever I turned my head, the seal would break, defeating the ANR.
My family spent a few hours walking back and forth between the booths at OSH one year. I could repeat the seal breaking in the Lightspeed booth, but couldn't in the Bose booth.
I know other folks that found similiar issues, specifically what may be comfortable to them, and came to different conclusions. Even with my family, we were split on decided which ones were better.
Bottom line, is that they are many good headsets out there. Some of the differences are going to be better options with different head shapes. There is only one way to make that determination. Find a friend with a pair and give them a test.
