Both are great choices. I've had both.
Duratrac on my 2007 Ram 1500.
BFG TA KO2 on my 2014 Grand Cherokee.
Both handle snow, and mud great. Both have good road manners, and are shocking quiet for an aggressive tire on pavement.
The deciding factor for each.
The Duratrac is known for having a thin sidewall. This keeps the weight down and softens the ride, but it also makes them vulnerable to things like beaver sticks, or a rock to the sidewall.
The KO2 is a little heavier, but can be a bit more durable. Based on my experience they're also slightly quieter, but that may be because they were on a Grand Cherokee versus the Duratrac's being on a Ram. So that make the sound comparison a bit subjective. Either way, both are really good in that department.
FWIW, these two tires are my top 2 for when I replace mine. You'll likely be happy with either one.
