    Based on accuracy, Bernoulli appears to be the better classifier, however multinomial beats it out based on AUC. This is to be taken with a grain of salt, as a study [2] does not believe "standard auc is a good measure for spam filters, because it is dominated by non-high specificity (ham recall) regions, which are of no interest in practice."
