Camac Terras have been about for years but get mixed reports. I have a friend, who's opinion I rate highly, that swears by them, but a number of friends who swear at them!
From personal experience on slightly larger 4x4s (Shogun, Trooper, LR etc.) I rate most of the main manufacturer offerings. BF Goodrich and Goodyear being my two favourites in the AT space.
If you want to save money then a remould might make sense, but they don't last anything like as well as a first life tyre.
