To my ears, the 007 is a more neutral tonally, but the 009 pulls me in to the music and makes me pay attention. If the music is background, I would prefer the 007, but if I am listening, I prefer the 009.
I have observed the same thing in general, though to my ears, the LCD aren't in the same league as the 007 while the HD800 is in the same league as the 009, though bested in almost every way by the 009. There is also the "minor" issue of comfort. For me, the the LCD are as heavy on my head as they sound to my ears.
