Well, these polls will be skewed by module distribution. If many voters don't know a good module, it will not get many votes. I don't know all the modules, so I won't vote. Instead, let me give a negative vote: I ran Wizard's Amulet as a lead-in to Crucible of Freya and didn't like it. It's basically just two encounters. The background story and the backgrounds for the pregen characters was great fun and has influenced the game for many sessions. But the encounters themselves... Meh. And you're better off recreating those pregen characters. They were created using 3.0 rules and some of them have incredibly high ability scores.
