When I was searching, it ultimately came down to value, comfort, and sound protection. I think I really just didn't want to spend the money for the Bose even if it was the slightest bit quieter.
Others I considered along with Clarity Aloft were Lightspeed ANR and D&C ANR. Of those two I would have chosen the Lightspeed because of comfort and sound reduction. All of these were in about the same price range (lightspeed was cheapest actually). Clarity comfort really makes the difference in how I feel after a flight simply because of the lack of weight on my head.....
One of the other flight instructors that got the Clarity at the same time as me tried them on in a Cirrus then to test, put the BOSE on OVER it....he said the bose eliminated some more of the low frequency but leaked in more of higher frequencies when he removed the Clarities....
All of those headsets are quality and are among the best in hearing protection in my opinion....any would a good choice, just depends on what you are looking to spend and how strong your neck is
