Commander Pre-Cons- Which is Best and Why?

When most Magic: The Gathering players hear the word “pre-constructed”, they can’t help but laugh a little.  Not only are the pre-constructed decks rarely any good, but the rares provided in said decks are often cards that have no chance of being desirable in any meta game.  With that said, I was elated still at the announcement of the commander pre-constructed decks that will contain NEW cards, never before seen, alongside a plethora of presumably useful cards in the format.  Boy was I not disappointed.
