If you are talking about radiation energy then a vacuum is the best medium for propagation as it provides no means of absorbing or dispersing the energy. Consider star-light and how far it goes without getting depleted or corrupted. If on the other-hand you are interested in thermal/heat conductance, Diamond has the highest value I could find, with a transfer, or thermal conductivity value of between 900-2320 W/(m*k) Just for reference, Pure Aluminum only has a value of 220, While Copper is 380, and Silver is 429.

Air is also a poor conductor of heat.

of the heat to its destination, and there's none of that in vacuum.
