With the standard stat, you are fine in normal driving. Temps are not an issue. What we want is something to prevent temps from getting too hot. Like heavy traffic.
But as soon as the temps start going up, the differences between the two stats fairly rapidly become moot.
So yes, most of the time in normal driving, the low temp stat means lower oil and coolant temps. But to no advantage because the standard car is not running very hot either!

You don't see running coolant (and by default the oil) at 205+F all the time as running overly hot? Again, it is easy to observe the difference in how the oil feels about it as cars running the OEM stat show lower TBN values, and often have their oils "fall out of grade" at much lower mileage intervals than cars running the same oil but a lower temp stat. It is also interesting to note that Porsche's "max effort" cars, the GT2, GT3, and Turbos,
all run 160F stats from the factory.
