Yeah, looking into tires can drive one nuts.
You are missing my current tire, which is the Mickey Thompson ATZ P3.
Your tires belong to two sub-categories:
Lighter duty for the Toyo and Falken and heavier duty for the ATZ P3, the X-AT, and the KO2.
Of the latter, the KO2 is easy for me to discard.
So that leaves the ATZ P3 vs the X-AT.
They have the same full 32" height and seem to have the same weight. Both have a 3-ply sidewall. Both should do better in mud than anything else on your list.
I can say that the ATZ P3 has surprised me for how civilized it has been on road, at least on stiffer suspension. I don't think any E load will play nice with the soft stock suspension but I can be wrong
Off-road, it offers total peace of mind and does great at 21 psi. Short of deep sand and the like, it can do just fine at 28 as well, just less comfort over rocks.
I am not sure I have a strong opinion about ATZ P3 vs X-AT.
