Anyone running delo in the 4.0?

I know rotella is a popular match for this engine but delo has more zinc more phosphorous and significantly more moly, boron and magnesium. Rotella does have a higher tbn and more calcium. I feel like most people choose rotella because it is easier to find/cheaper. Is there another reason to favor rotella over delo?

It doesn't really matter. Filter choice is much more important than the choice between those 2 oils.
