User blog comment:LexiLexi/10 Reasons Dumbledore is Cooler than Snape/@comment-1590788-20110902230924

Dumbledore can't direct every step of Snape when Snape is with Voldemort. Then Snape is alone and must do what he thinks is right. He then can't run to Dumbledore and ask him what to do. So I think Snape's genius is as good as that of Dumbledore. But that's only my opinion.
