The two headsets both work well but they do differ regarding passive noise reduction. The Bose does reduce the noise levels to a greater degree. If you are going to use it for GA ever, I would go with the Bose, otherwise the DC is fine for jets.
It’s a trade off, the DC is lighter and slightly more comfortable for an eight hour day. That said....even in the jet, the Bose is quieter. At that point it’s a function of the other guys mic if your using an intercom. That’s where you get a lot of the white noise.
