If you want the best traction during winter months then you gotta go with the duratracs. They are designed to perform amazingly well on wet roads due to their softer rubber texture and aggressive pattern. These tires are impressive in road handling and in the snow they turn "beast mode" due to in part of GY's self cleaning technology. Visually they look mean and beefy like they have plans to eat your newborn child. The only problem I have is that these tires will wear out much faster than the BFGs, not a deal breaker since they are a bit cheaper. Duratracs overall are excellent tires, they weigh less (may save you a little on MPG but who is really counting, lolz) and look amazing on any rig.
Now for the BFG T/A KOs, if you want some trusty shoes that will perform extremely well all around in any scenario (badged A/T for a reason), much like a swiss army knife, durable as hell and will last forever and a day, get the BFGs.
Also an important note, the Duratracs have a good amount of road noise at higher speeds compared to my BFGs. It's noticeable and makes my BFGs sound completely silent. This is all from my personal experience and can be the deal breaker for some. Not a big deal for me. I'm lucky to own both tires and in the 265 size.
If I was forced at gunpoint to choose between the two, I would get the BFGs but glad I don't have to make that choice!
