probably gonna catch some flames, but the Lee PPM!
I haven't used another powder measure, but from complaints of other manufacturers I can say this about mine with confidence:
It measures stick, flake, and ball powder very accurately and consistently regardless of powder level.
Never had an issue with static electricity.
No baffles to fudge with or lose.
I can close the powder hopper, remove the entire hopper, and empty it back into the powder jug when I'm done loading.
They're cheap so I can buy multiples, set up for my favorite powder charges in pistol and rifle powder.
