Brogueing is the holes punched in the leather, not the style of the shoe. A more formal Oxford, with closed lacing, can have brogueing. And a less formal blutcher can be plain, without brogueing. It's more about the lacing, open vs closed, that makes the formality of the shoe. I think if you want a black dress shoe for weddings, funerals, etc you definately want the more formal Oxford. Brogue or not is up to you and your taste.
