I use both the Wonderdogs and clamping elements all the time - couldn't live without them. I also have a pair of the Jorgensen hold-down clamps. The clamping elements are fast and secure, but they don't have the horizontal accuracy of the Wonderdogs. I use the Wonderdogs to snug things up to the cut line (pushing from the far side), or holding pieces in a very stable accurate position. The clamping elements aren't quite as good for this, with their rubber plates and sliding elements. They all have their place on the MFT!
