Victorias Secret Perfume Scent?

Okay so I want to get the Victorias Secret Dream Angels Heavenly scent however I do not know if it would be best ot get the eau de Parfum or to just go with the mist. Has anyone tried this perfume and do they find a difference between either the mist or perfume (smell or lasting time). Which would be the better bargain??? The perfume for $42 or the mist for $25?
