The answer has to be ONE Touch. But even at that, there are a couple of subtle differences to be aware of.
My one touch is a Nikkor zoom and it is a push-pull function for the zoom, and turn for focus, when using manual and not auto-focus. In auto-focus mode, then it just becomes push-pull for zoom.
However it is possible to have a two touch zoom, both focus and zoom being rotating collars. However if this is also auto-focus, then in essence it becomes a one touch zoom, but the one-touch is a rotating zoom, NOT push-pull.
Note that my personal preference is for a push-pull zoom action. I think it is just faster and easier to use.

No DSLR, but regular SLR for the last 20 years...
I've used both push-pull and rotating zooms, and I like them both. Rotating zooms are more precise and not subject to the zoom creeping when you hold the lens barrel up or down from the horizontal.
push-pull zooms are indeed a bit faster to use, but mainly that's practice.
