They all have their ups and downs.

KM2 is a great tire on and off road, but they do tend to have a weaker sidewall, however more aggressive and stronger than your duratrac.

Kevlar is a great tire offroad, in my experience they always tend to start cupping/feathering within 5-10k miles. You need to be religious about rotations, and it's still probably going to happen.

Nittos, Don't look at the mud grappler, look at the trail grappler. I think these are a great all around tire, work well offroad and kick ass on the road. They have just about everything you're after but do tend to be a bit pricey.

I had a set of hancooks, I loved them, but I did kill a sidewall and wasn't that hard on them offroad, mostly tahuya and snow wheeling. I killed a set crossing a small stream in the snow.

cooper STT seems to be a decent tires too. Similar to the nitto/toyo MT but softer compound.

Trxus M/T work awesome, but again have a ridiculously soft sidewall.

My vote assuming you are going to be putting more than 75% road miles would be between nitto and BFG
