I haven't had to replace tires yet, so I don't have much comparison data. From what I have noticed:
-I'm from Oregon, about the rainiest state you can choose. These tires do fine on the road.
-I have 22k on them, and they seem to be wearing about the same (maybe better) than a MT tire. Maybe it's just me hoping they wear fast, I kinda want to try something else...
-I'm starting to do a decent amount of wheeling, I plan on at least 1 trip per month. I've gone in snow, mud, and dry dirt. I can't give testament to rock gardens. The hardest I've done is trails rated moderate at TSF in muddy conditions. I would say that I have a bit more difficult time than a more dedicated offroad tire, but with the capability of the truck and airing down to 20PSI, I haven't had need for a winch.
from my last run at TSF. It was very muddy, and the pics don't do quite the justice - anything brown you see is slippery mud. I'm in silver, RelentlessTaco is in white. On the second to last pic, I had to turn on the locker to reverse up the hill to execute a turn. RelentlessTaco's a much more experienced driver, and doesn't have a locker. Whether he chose a better line or the tires were simply that much better, I don't think his BFG KMs ever had a problem. Note that it was actually a bit more hilly than it looks in the pic.
-For snow, slapping on some chains at each corner and airing down makes things stupid easy, at which point the tire doesn't make as much difference.
-I think they have a decent curb appeal. I like white lettering, and on a stock vehicle they provide a much better look than the dunlops.
Considering that you don't really offroad, if I were in your shoes, I would scour for some Rugged Trail takeoffs. You could pick them up for incredibly cheap and they should be in fairly plentiful demand.
