Here's my opinion.....take it or leave it.
General Grabbers are definitely a good looking tire, but are heavy and are consistently not good in anything but sand.
Toyo MT's are also a "looker" tire that is CRAZY HEAVY.
I wouldn't get either of those.
Goodyear Duratracs are great in the snow, but rarely go past 30K miles from what I've seen, and have weak sidewalls. I also think they are hatchet wound ugly.
BFG KM2's are a good tire, not great in snow unless you have them siped. Great in all terrain and I had 40K on the set I just took off my truck and there is still 60% tread left. Great tire IMO.
MT/R w Kevlar. Little more aggressive and heavier than the KM2 but not bad. Not great on ice/snow. Great in the rocks with strong sidewalls. Rarely I'll hear experience like BFoster133 posted where the tires wore out fast or had blown sidewalls. Personally I think the fast wear is because how the tires are being used, i.e. low pressure over fast terrain, lots of wheel spin in the dirt etc. And the blown sidewalls are just unlucky and would happen with any tire. Even looking at BFoster133's sidewall gash you can tell it was a sharp rock or something that hit it to create a relatively clean gash.
So. General Grabbers - I would not buy them
Toyo MT - Definitely would not buy them
Goodyear Duratracs - You couldn't pay me enough
BFG KM2 - Yep I'd run em. I have and probably will again.
Goodyear MTR Kevlar - running them now. So far so good and really liking them.
