I definitely recommend spending extra on ANR equipped headsets. The particular one you buy is up to you, whichever you can afford. If price isn't an issue, go for the most comfortable. I have a DC that I've modified using the Headsets Inc. kit to ANR spec, and I swear by it. I've also flown with Lightspeeds which are much lighter, and initially more comfortable, but over longer flights I still prefer the DC. I think they're all pretty good (Bose, Sennheiser, Lightspeed etc) but the comfort and fit is key.
