All: I have and use both, mostly as 'sitz' pads in camp or on day hikes, also Evazote as a full-winter pad under a Thermarest LE.
All of my foamies come to me used, some with much use, and the Evazote is clearly superior over the longer haul; it is harder to rip and to crease by folding. It is also more reliable (and warmer!) below -25C where most plastic products get dicey.
Your experiences may vary!
