wax or sealant?

So I'm in the process of putting together the products I'm want to use to add my full correction package, and the only thing I haven't decided on is whether to use a wax out a paint sealant. And if wax, carnuba or synthetic. I know you can top carnuba with sealant to make it last longer, I know all the book definitions of the wax vs sealants and all that, but I'm wondering what you guys think about it?

Duh, that's what I meant... It's been a long day...lol
