Now if you had said temperature in place of heat your statement would have been correct, though irrelevent.

in convection, yes, conductivity is the more important factor. Hence my saying that in most applications of this type (heatsinks), copper is the better material. I was merely stating facts that i believe lead to the perception that Al dissipates heat better in a heatsink type function.
