I'm with you Teabag. After our last set of MTZ's we are now the proud owners of a new set of ATZ 4 rib. They look great, have the most aggressive tread for an AT tyre and I'm a fan of their side wall protection system which is patented. After Three sets of Mt tyres (1 ATZ 5 ribb, 2 MTZ and not one puncture I reckon that's good stuff. The new set are 2 weeks old so time will tell.
Wat he said, ive had BFG AT's and they were great 80000k plus wear, also ran 694's on my Patrol 50000k wear and plenty left, but of those 2 for an AT tyre not all that aggresive without going to a muddy.
Ive just changed to a MT 4 rib ATZ, based on being a bit more aggresive in pattern without being a muddy, plus all of the great feedback on them, IMO, i discounted the cooper tyre based on feedback, at the end of the day there is heaps to choice from and your budget will most likely be the governing factor.
Good luck with your choice.
Swanny.
P.S. u get wat u pay for.....
