AL vs. Copper radiator

I was reinstalling my stock mechanical fans the other day and noticed that my radiator is copper vs. Grant's (97 supra) radiator that was AL. Copper conducts heat better than AL which would lead me to believe that my radiator is better than his. I was wondering, is this the case?

Is a fluidyne really that much better than the stock copper radiator? I just replaced my water pump, reinstalled my stock fans, and cleaned my cooling system and I am still having issues. Today my car began to heat up while idling for a while with the AC on. As soon as I reved the engine the temp gauge dropped, but it still heated up.

Does anyone have any suggestions?
