My first set were MTR's, great traction / good road handling / fantastic durability. Ran over a wood pallet at 65mph, imbedded (without me knowing at the time) a shard the size of my pinky into the tire. Drove another 20 miles and the tire didn't go flat until the middle of that night. I was very impressed
Second set were ProComps Mud Terrains, got a good deal on the '4 for 3' sale they have periodically. Traction is excellent, quite loud as they get older. No issues on the trail doing heavy rock crawling.
If the prices were the same, I would go the MTR route today all things considered.
