The newer KO tires have mixed reviews, but most like them. However, BFGs are not cheap.
I've heard good things about the Defenders. However, I can personally testify that Michelin LTX AT2 tires stink in the snow. I had them for a bit, got a good deal... and there was a reason I got a good deal. Anything more than a trace of snow, and I was all over the place. They were good in the rain, and when dry, but terrible in any snow or mud. Definitely more of an all season tire then an All Terrain.
There is no wrong answer here, as long as you are happy. Falken Wildpeaks, Hankook Dynapro ATm, Cooper Discover AT3, BFG KO, the Kumhos, etc. With a LT sized tire, you will have a little harsher ride, and have to put more air into them (my LT sized Hankooks are happy around 55-60 PSI versus my wife's P rated, which are happy with about 40 PSI). They are also heavier, so you'll lose a bit of MPG compared to P rated tires. However, they are thicker treaded, thicker walled, and unless you go rock crawling on a serious Jeep trail or do something ridiculously silly, I doubt you'd puncture the sides.
