Different headsets for different jobs. It seems like the inner ear ones I see other guys using tend to have issues with the wires rubbing through. Someone with a pair could probably better tell you about that.
As far as the long run goes you kinda answered your own question. In my mind as far as ruggedness goes nothing will ever outlast the DCs. There are better headsets out there for noise reduction and other gadgets like bluetooth but when it comes down to which set you can throw in the bag and you know will work next time DCs get my vote. Flying in the airlines my next set will probably be a Bose QC15 or whatever the new setup is but from past experience I can tell you they simply don't hold up as well.
