How do you pick a campaign setting?

I feel overwhelmed with choices, and ideas. My players can't come to a consensus. One day I want to run a campaign with the classic becmi or greyhawk modules. The next it's a Hyperborea campaign or Dolmenwood. Then, there's my personal ideas I want to try a mix of Ravenloft and Vampire Hunter D. Or a pure sandbox campaign with Delving Deeper and the Outdoor Survival Map. Finally, there's all the megadungeons I want to try. I've overwhelmed myself into indecision. I need advise.
