I would say neither. I think Sansabelt pants are the best quality and long lasting pants. I have Sansabelt pants I have had for 10 years and still look very good. I had pair of Cliff Keen that busted out in the crotch (jokes please

) after only a few years. Maybe the quality has gotten better, but they seemed a little flimsy to me as compared to the other pants. Smitty pants are another kind I have had and closer to Sansabelt, but I have only had them for a shorter time. I guess if you held my feet to the fire I would go with Smitty brand but when I have the chance I buy only Sansabelt for the long lasting quality. I have also fluctuated in weight and they still hold their shape and fit very well.
Peace
