Cooper at3 or toyo at2?

I have had 3 sets of BFG KO1 and they all went over 60,000 miles. Got the KO2 now. All around great in my opinion. If I lived in a place with mud and snow I would probably get Toyo R/T

 

We have 100's of trucks at my job. All have bfg ko's and are slowly getting switched over to ko2's as they need replacing. We can't get 30k km and they are toast. Gravel roads on a daily basis eat ko's. Lots of experience with them.

I have friends that use their personal trucks mainly on road and ko's last a long time for them. Maybe why ko2's last twice as long on gravel roads bfg claims, obvious they saw an issue

 

*update*
I went to purchase the coopers and the tire shop had 25% off good year duratrac's. They are a nice looking tire, and have the snow flake rating.
