DP side mount radiator is aluminum or copper better?

As with most things, it not as simple as which one is better. Copper conducts heat better (water to metal), but aluminum transfers heat better into the environment (metal to air). The real key is heat dissipation of both radiators, which considers many different factors (ie: materials, size, number of rows, fin design and spacing, air flow, etc). Do the manufactures provide any info on total heat dissipation?
