The nice thing about the Dime Wah is that it has a contour dial, so you can set it for a mellow sweep where the effect is subtle, or a peaked sweep where it kind of 'quacks'. The first is good for guys that play relatively clean, or really like to use the middle regions of their wah. The second is good for guys that are playing funk, or are doing high gain leads and want the toe to heel transition to stand out more.
Additionally, there's a knob that sets how bright it gets in the toe down position, and a knob that allows you to add some clean boost to it.
Last is the Q knob. It lets you go from a bright, cutting wah sound to a dark, throaty wah sound. I find this feature pretty handy. I have mine dialled in as a pretty Cantrell-esque kind of sound, but sometimes I need a bright, more cutting sound so I can just reach down and change Qs and it's like I have a whole new wah.
I have a Fulltone Clyde Deluxe as well. I think it's a nice wah. Very clear sounding. However I sold it in favour of my Dime wah. It ships today.
