Elp,
You and I have been around this forum for a good while. I read your lengthy essay above, and all I can say is you have no clue what you're talking about in this case.
More claimed power in S65, yes, 2hp and 100 ft lbs less torque.
"Drives like a truck," you're out to lunch.
Have you even driven a 2011 5.0? It's not the same car it was a few years ago. The best you can objectively say is that the are approximately equal performers. As for what is more satisfying, that gets a little more subjective, but having just climbed out of an M3, I find the '11 5.0 more satisfying.
Your credibility is straining here, buddy.
