Lonnie, Garrett et al,
Fun to watch you guys rehash this age old argument. Really I'd say it boils down to finding what entertains you and going with it.... even if what entertains you is 'debating' in an internet forum.
My take on the two series is... they're both corrupt. Too much $$ at stake not to be. They both have sanctioning bodies that enjoy wielding too much control.
The passing issue really gets me. Yes, I wish there was more passing in F1, and I'm really hoping that eliminating a lot of the aero next year will go a long way towards accomplishing this. But really.... all the passing in NASCAR makes it exciting? I don't get that at all. In F1 the value of a pass is really high because it's so difficult. Yeah you might only see a half a dozen quality passes in any given race but these passes take tremendous skill and courage. In NASCAR it's so easy to pass that I don't see it as exciting at all. The first time I rolled my eyes at NASCAR was in the seventies when the 'slingshot' was so unstoppable that the competition was to see who could get themselves into
second place before the final set of turns. I agree that team orders in F1 are frustrating, but what about seeing the leader of a NASCAR race slow down to let his
competition pass? I'll take a few passes that leave you aghast, wondering 'did he
really try that? and it worked??' over a ton of passes that any decent driver in a strong car could have pulled off.
I find the broadcast team on Speed to be very entertaining and often very insightful. Bob Varsha has come soooo far. I think he does a good job of calling the race and when he offers insight it's usually spot on. I remember when he seemed like another stick and ball guy covering a race. Oh, and the English accents do sound intelligent, don't they? Not to disparage the intellect or skill of the NASCAR announcers.... I guess they're just not my cup of tea

I also think the skill of the drivers is superior in F1. Certainly this could be debated but jeez, just watch the NASCAR guys when they have to turn right, brake and shift. A few of them seem to have had some training, but most of them are nothing more than an embarrassment to themselves and the sport.
But hey, if you want to see some real racing, take a trip to a local road course and watch them run what they brung. Pick a series where the typical owner/driver has less than 50k wrapped up in the car and a win pays less than 2k. Now that's racing for the love of racing.
As far as F1 vs. NASCAR, I think it's really which circus do you prefer to watch.
