There's about as much BS in an anti-seize discussion as a K&N air filter discussion.

But...what I have gathered over the years:

-Aluminum anti seize is the best all around. Not good for high heat such as exhaust parts however.

-Copper anti seize for high heat applications. Do not use copper on aluminum.

When using it on anything going into aluminum use aluminum anti seize, dissimilar metals thing.

Most spark plugs made today have a special anti seize plating on them and anti seize is not recommended.
