Yes, I've always been attracted to the Benbo, but it seems a little unwieldy. The Giottos seems to function more like a normal tripod, plus you get the adjustable lateral arm. I believe you can also remove the center column and mount the camera on the top plate, and use it without a head (I think you can tilt and pan, but not level left to right this way), which suits my two Gowland cameras fairly well.

I handled the Carbon One at B&H and it seemed too light to me.
