True, but i havent started a thread in a while and wanted something with some substance.
But i was more hoping for an argument on why one is better than the other for such and such reason(s)

Epic fail. The saying "oil is oil" is a joke. I would never run anything less than a full synthetic in any car of mine that is driven hard. Conventional oil is wax based and cannot travel into and protect certain parts of the engine like synthetic oil can. You may not see the wear, but if you were to compare two identical motors (size, mileage, hp) with one running conventional, and another with synthetic, the physical results would speak for themselves (and they do).
The molecules that make up synthetic oil are smaller which is what gives it those capabilities. My truck is well past 100K and the valvetrain and motor noise in general is very quiet in comparison to all other 5.3 Vortecs I run into that service with conventional oil, and they have 1/2 or only a 1/3 of the miles I have on my motor. And considering I work in the business, I've had plenty of different trucks to compare to, on a daily basis even. Come on Mr. "World's Greatest Mechanic" ! You should know this! (I kid, I kid)
As for me... I generally ran Mobil 1 and nothing else in all of my cars ever since I had a driver's license. For the past couple of oil changes I have been using Castrol Edge 5W30, and plan to stick with it, Judging by the tests as well as my personal experience so far. The Vortec motors in the GM trucks are notorious for burning oil and mine would eat through about a quart of M1 every 3K or so, roughly, regardless of weight, and would get dark very quick. With the Edge, it only ate about about a 1/4 of a quart in 4500 miles, and the color looked much better than M1 did at that mileage. So I'm sold.
Syntec is a step below M1 and Edge, but is still good stuff. The German 0W30 appears to be the best of the bunch, but someone I knew with a C5 LS1 Vette decided to try out the GC and was not happy with it. Said the valvetrain was way more noisier as opposed to when he ran M1.
But in the end, oil opinions are like any other opinion on anything else. Its all really preference and as long as you run a synthetic I think you're good.

I spin my stock bottom end to 6500+ rpm on a daily basis and I average 25k miles a year...using Valvoline conventional oil. I have 187k miles on the original manual transmission using conventional ATF (also Valvoline). The whole "you must use synthetic" is a joke to me. But as you said, that's my opinion.
Also way to over use "epic fail"...using 75w90 gear oil in your engine = epic fail, using convetional 5w30 is not...
Just to be clear, I'm not saying conventional is better, just stating that I use conventional and I don't have a reason to spend more on full synthetic. I don't expect my engine to last forever with the abuse I put it through, it will fail in other ways long before the bearings give out due to any sort of under lubrication, if any...

Me personally, I only want the best in my babies. I want what will minimize or nearly not wear out my motor, and maintain HP longer. Not what will "just make it run."
That's why the big quote for Castrol Syntec is "provides horsepower longer." It's not a sale tactic, it's proven. Synthetic oil leaves virtually no wear behind, so the motor will perform and run at its best for nearly its whole life.

I would argue and say all top brands of synthetic yield the same results... with the exception of royal purple being overpriced because, well... people seem to keep buying it.

based on a thread ive read on here (somewhere)
extensive testing has shown that German castrol and penzoil platinum are the two best oils you can put in your car
although from personal experience i like the gc better, the pp seems to have a weird smell to it and seem that my car burned oil much more with it(well more then normal)
but the price can not be beat with the pp only around 25$ at walmart (and the gc around 45 at auto-zone if they have it)
and btw dont ever run synthetic or royal purple atf in your t56
