Another extremely tough decision... but my vote goes to Gonadz.
Reason: Ryoko's BG is what I and many people, who know of his style, expected. The image is great, so great that it demands a totally different color tint around it. The purple struggles to blend with dark red aura the image subcounsciouly screams for. Also, I won't hesitate in saying that you were as professional with the font, as you have always been.
Gonadz, this sig is very unique for this forum. It might have required less effort, compared to Ryoko's, but the well-placed brush work is what really gives it a fresh impression, the font for "Lost Prophets" being what sealed the deal for me. My only beef is the placement of "Nadz", and the font you used.
Score:
Gonadz: 1
Ryoko: 0
