Both coals are fossil fuels.

Which coal has least moisture content?

anthracite coalLump of anthracite coal. Anthracite is a dark black form of coal and the highest quality coal. It is very hard, has a low moisture content, and a carbon content of nearly 95%. When burned, anthracite can reach a very high temperature.

Which coal has highest ash content?

AnthraciteAnthracite is the highest ranked coal with the carbon percentage of above 87%. The carbon content in bituminous is 77-87%, in sub-bituminous is 71-77% and in lignite is 60-70%. Lignite has the least carbon content and hence highest ash content.

What is the hottest burning coal?

Anthracite coalAnthracite coal is the hottest burning fuel in comparison to the most common ones in use. Environmentally cleaner than other fossil fuels.
