I haven't tried the Mickey T's or Coopers, but I do have approx 15000 k's on my 32x11.5x15 BFG KO2's and I love them.
My experience has been - No punctures / staking (touch wood)!! and excellent traction in sand, mud, loose rock, pea gravel and dry and wet roads. They still look pretty good after 15000, no torn lugs or anything, and I have used them on some unforgiving surfaces. Slightly more noise than my previous Bridgestone Duellers, but not bad, (a little more noisy in the wet, don't know why).
A few of my friends also run them in 32 and 33 inch sizes, on Cruisers and a Triton and all have told me that they love them too. (Including one who went across Oz, up to the cape, Oodnadatta, Birdsville, Big Red etc.
I would buy them again for sure.
Just my experience.
