I would bet most of us use synthetic motor oil, trans fluid, and diff fluid. It just doesn't generally happen to be Royal Purple for said fluids.
And I agree with Tom. Personally I'll go with the safe play vs the one that isn't. Even though something else may work just fine or better. So for now it's Redline oil (full of ZDDP yumminess), Castrol trans fluid, and Mobil 1 diff fluid. I keep thinking I should go to M1 high mileage engine oil, as it has the "normal" amount of ZDDP and is cheaper, but something about that "high mileage" in a 40,000 mile car that I can't explain bugs me...
