EHB can be just as mean AHB depending on the circumstances. It is just that EHB are less likely to be overtly aggressive. Also AHB don't tend to be highly aggressive until theyhave a nest to defend. Swarms of AHB behave like EHB and AHB swarms tend to be smaller.
The worst attack I ever received was EHB when I dropped the hive.
