I have run both, I currently have BFG A/T's on a landcruiser, fairly manageable and responsive on the road not much noise , slight breaking issues.... the M/T's were different - they hummed pretty loud on the highway and they definitely effected breaking and steering - took some getting used to. Both have good sidewall strength, the AT's are enough for me now, my off road days are over.
One thing to consider is the width, I always felt better with narrower tires, the 12.5's that some guys run always struck me as too heavy, affecting steering components, breaking etc..... I never saw a huge benefit to the wide widths unless maybe doing some serious rock crawling. Maximum width I would run is 10.5 but even that I am not sure of ....I am looking for 9.5's for my "new" 1985 F-250. Currently the 250 has Alcoa rims ( 16.5" x 8 or 10"?) with BFG A/t's. They are way too wide and heavy for my taste. I cant comment on performance because I have not really driven the truck with them on, also they are pretty beat.
