You are trying to compare two completly different worlds... the Continental ones are like a Freelander and the MT-R's are like a Defender. You can go in a really smoot way with the Conti, they are quieter, safer and have a longer life than the MTR. If you want to use the Defender to their limits, you have to go for the MT-R. In any terrain, the MT-R and the BFG are really good, both equally capable. I have seen both in action and have something in common: both tyres were better in their former path, new ones are not as good in off road, both are better now for the road.
I have in my car the former Pirelli Scorpio AT, they were in the top-5 AT tyres. They are smooth, really safe, very quiet and can have a hit in the mud, but not up to the task if you want to use your Defender to their real capabilities. The Conti come as standar in the Kia Sportage they sell here in Colombia, so they have to be really good on road, but for their off road abilities....:(
