I smell a nice controversy here, so in I go with both feet: I prefer two-ring zooms to the one-touch type. I've had both - although I have only two-ring lenses now - and I found that the one-touch design tempted me into fiddling with the focal length at the same time as trying to focus. I also tended to forget which way was push and which was pull - I had a telezoom where I had to push the barrel out to bring the world closer, which felt wrong. With a two-ring lens, I tend to select a focal length (say, 24mm - the M24-35 is my most-used zoom too) and then concentrate on focusing and composition.
Incidentally, does anyone know of a one-ring AF zoom? I'd imagine the combined focus-zoom assembly would be too much for a focus motor to move, but you never know.
