My big choice between copper grease and anti-seize on a seized seatpost

I spent last weekend trying to pull a stuck aluminum seatpost out of a steel frame, and I had to decide between copper grease and regular anti-seize for the reinstall. I went with copper grease because I heard it handles heat better on older bikes. Has anyone else had better luck with one over the other on seized posts?

...and that's exactly what I said to my buddy when he handed me a tube of copper grease for my own seized seatpost nightmare, like "oh great, now I get to play chemistry teacher on a stuck tube of metal." I mean, I'm still not convinced it's not just fancy snake oil that smells like a mechanic's garage, but hey, it's been a year on my old Schwinn and the post hasn't welded itself back in yet, so maybe that heat thing works. But honestly, I think half the battle is just remembering to put something on there instead of just cranking it in dry like I did the first time and then spending a Saturday with a torch and a pipe wrench trying to get it out.
