I really don't get why so many of you are taking what I said to heart? It's my personal opinion, leave it at that.

It only makes sense to compare the M5 to the S8, they're not very far off competition wise, both upper crust sedans w/ V-10's capable of running w/ sports cars(M5 at least), and lastly, there's no direct competitor from BMW to the S8 from the current generation 7 series.
