    Heuristic detection is basically detection by behavior. A lot of activities are normal for both malware and legitimate apps. It's only when the whole chain of activities are viewed that some malicious behaviors become apparent. They've (malware writers) have gotten good at hiding shifts and jumps to other parts of the instructions in ways that aren't obvious to people or the analyzing software. They're also encrypting and obfuscating parts of the code in ways that make it very hard to tell just what it's trying to do.

    As for which is best, that probably changes with each revision of the AV and the type of code it's detecting. I don't use an AV so I can't recommend one over another.
