You sound like you have a case of OCD, so I'd recommend you go find some Red-n-Tacky so you'll feel good.
For the average Joe, if it says 'for wheel bearings' on the package, it will work just fine. Any extra special magic in the boutique brands is over and above what you need and won't make a difference in the real world.
FWIW, NAPA is good grease, but honestly you'd be hard pressed to find any 'bad' grease. Wrong grease is a different story, just make sure what you use is intended for the job you're putting it to. I use Walmart moly on everything, 'cause that's how I roll. It exceeds requirements for everything except the birfields, where it only meets the requirements. Even there, it's probably better than anything that was available in 1997.
