I'll be honest, I like just about any good coal. Whether it's worth it depends on a number of factors including cost, for some people cost is by far the biggest concern. There are many good bituminous coals, but the one place where the best bituminous coals are located is eastern KY. A good eastern KY coal will be "better" than any other north american bituminous coal for home use. It's high volitile and easy to burn and light, but releases it's volitiles more slowly than other bituminous coals, it generally has substantially less ash than other bituminous coals, it often has a few thousand btu's more per pound than other bit coals and perhaps most importantly, it is a "non-caking" or low to 0 coke button coal, which is unusual in eastern coals with high btu's and low ash. A good bituminous stove or stoker and a seasoned coal burner will be able to enjoy burning any GOOD bituminous coal, but for people (most) that don't have a very good bit stove or a stoker, or for those just starting out or trying bit coal for the first time, the learning curve is much, much easier with a good KY coal than any other north american bituminous coal.
