Recommended fluids for GEN1 Raptor-OEM or aftermarket?

[Stingray23]

I'm getting ready to flush all the fluids(not oil) in my truck and would like to hear what you guys think about using the OEM stuff or Amsoil or any other brand. Will it actually make a difference? Is the OEM stuff more than good enough?

OEM has gotten your truck this far so why not keep using it? Staying with OEM will most likely save you money and do just as good of a job.
