I've only ever heard praise for BFG MT's.
My dad has the Colway MT's on his Rangie and you will certainly notice they're on there, but as he says "for £45 a tyre who gives a ...?"
IMHO they're no worse than the cheap kwik-fit road tyres that were on there when he bought it, at least with MT's you don't expect them to be any good on the road.
If you want to drive like a loon stick with AT's, if you can accept either having to adjust your driving slightly, or enjoy power slides, fit the MT's
