Back to the original post. Sorry but to me this is like comparing apples to oranges to bananas.
(Wings vs regular sprint cars vs midgets)
Or just leave USAC out of the mix.

Unless you are talking about the smoothness/fairness of officiating
and the actual putting on a timely, well organized event.
Even then, I rarely go see wings or care to.

Perhaps comparing USAC to MSCS to WAR is more of an even playing field.
I will opt out now.
