Don't take this the wrong way but I doubt any of you as consumers would be able to take any discernable or noticable differance in the oils you use. It only really comes to be noticable if you begin to analyse the oil routinely and gather performance data.
What I'm saying is don't get 'sucked in' to brand names or what others suggest is good, it's largely down to personal preferance and in many cases branding and percieved benefits (fuel economy etc).
Of course many different brands of oil have different properties which will be derived from the additive package used when blending the oil but as I said above I doubt in the context of an end user switching between service intervals you'll notice anything.
Go for one that meets the OEM specifications that is in the right price point for your needs.
Serious questions and not picking you out for anything other than curiosity -
I would use the Castrol Edge over the Quantum stuff
Why??
But the Fuchs Titan Race Pro is good stuff,
How do you know??
