I haven't tried the turtle beaches, but the logitech headset is a solidly build headset. Sound is slightly muddy with too much emphasise on bass, but an eq will mostly correct this. The only reason I got rid of them was that you couldn't adjust the mic enough so it always resulted in unclear/quiet mic inputs.
I can solidly reccomend the kingston cloud series of headsets. Sound wise, they don't have heaps of bass, with an emphasise on treble for a competitive sound staging.
