All depends on what you want to do. The Montucky is hard to beat if you're roaming the countryside looking for big game, but the Cooper has no flies on it either. If you're spending a day in the prairie dog towns, a Cooper has few equals this side of a full-blown custom. They are beautiful rifles that shoot very, very well. You don't see very many unhappy Cooper owners.
I can build better,for less than Cooper loot,which happens to be throated/twisted per whim.
Building heavy is easier,than building light and less expensive to boot...............
