Is RP fluids much better than GM fluids?

[rxis]

May be sort of a dumb question but are Royal Purple fluids much better than GM fluids?

I'm thinking about using RP for differentials and transfer. I may use it for engine just once. I want to try the hype at least once for the experience.

Royal purple is much better than GM's recommended oil yes. i have RP in all my fluids and i love it. my engine oil with 5k on it smells like new oil when it used to smell like shit using penzoil or other oil brands.
