The difference between this and the Kracken is that the Kracken has 4 hot ends in a very small space. 4x the heat in confined area without a easy way to direct airflow across all heat sinks creates a unique problem, one which water cooling addresses. For a single extruder/hot end on a normal printer, I don't think those same problems exist and therefor probably don't need solved.Quote

E3d are doing a water cooled hotend

They are made of stainless steel, not steel. Stainless has about 1/3-1/4 the thermal conductivity of high and low carbon steel.Quote

(steel is a much worse thermal conductor than aluminium, thats why the e3d heatbreak is made of steel).
Copper is much harder to machine than aluminum and it's not necessary. Plus as you pointed out would also be more expensive due to metal prices. The existing setup of aluminum heat sink and fan more than adequately cool the hot end. If you were pushing the envelope and needed the maximum amount of thermal conductivity to keep things cool (e.g. a CPU heat sink) then copper may be a consideration. But with aluminum being cheaper, easier to work with, and good enough to keep things cool with the fan, it's a no brainer which to use.Quote
If the effect could be maximized, I would use a copper heatsink instead of an aluminium one
