PYB is also a fine oil and will serve you well.
It's a quality product and the price is right. I do get a giggle out of some of the people on the 370 and G37 forums. They use boutique oils at a price that would make a Canadian oil retailer blush, and then change them out at 3,000 miles. Of course, their logic is unassailable. They claim that they cost more, so they must be better. They actually come out and say that!
There are indications the 3.7L is a bit harder on oil than was the 3.5L due to the VVEL. Fine. I'm still not spending $10 or more per litre to change it per the factory recommended OCI. If I'm going to follow their required service interval, I'll use a quality, conventional oil that also meets their requirements (and being SN, actually exceeds them).
