I would have thought that would be the other way around, the Coopers in that size 245/75/16 are a true 10 ply tyre, very very tough, and they have a rim protecting lip to help stop damage to your wheels.
Fouros and Ed do like their Maxxis Mudders as well.
Horses for courses really, buy what you feel you like best
a good MT will give you that little bit more offroad capabitity and thats what its all about.
