If you only care about DD stay stock. I've driven BFG on every 4X4 I've owned for 19 years, have them currently on my wife's Dakota and my plow truck F150 still. That said Duratracs have better grip on the sides and will be the new tires I but on my 2011 Sahara next mud season.
The only time I hear my duratracs is if the radio is off, the windows are down, and I really pay attention at 35mph. Any slower and they're silent, any faster and the top and wind noise drowns them out. They're very quiet tires.
The bfg's are louder but will last forever as far as tires are consirned. the duratracs are quieter and will still last you 40k+ miles. On road performance they are both good. Offroad the duratracs are a little better overall then the BFG's but doesn't sound like a concern to you
