I have not had both, but I think their performance is similar and the coopers are much cheaper. My opinion is that the Coopers look a little better and I did get through a deep mud pit with Coopers and another H2 with the Toyos didnt make it. That doesnt necessarily mean one is better, but mine seemed to clear out better than than the toyos than day. That is only in mud. I dont have any good comparisons on other types of terrain, i.e. rocks.
