I admit I haven't read all of it yet, but so far it seems to me this is more a FR comparison between the two headphones and not a test of their inherent capabilities. Might make more sense to compare them EQed.
In the end I'd still take my modded HD800 over either phone, but apart from FR I don't see why I would take the LCD-4 over the Utopia. The Utopia sounds weird tonally and the LCD-4 isn't that great either, tonally speaking.
Also all of the rankings feel too heavily biased towards the upper end of the spectrum, as if the lower 5-7 points were meaningless. For example comfort ... how the hell can a headphone even get a good comfort rating? If speakers are a 9 or 10 I'd maybe put the HD800 at 6 and Utopia at 4 (too much clamping) and LCD-4 at 3 (too heavy and too much clamp). It's never comfortable to wear headphones. I find my CIEMs much better and those are annoying too.
