I have a Lyman Brass Smith and three Hornady LnL powder measures. They all work well for me, and are very consistent with most powders I use once dialed in. Ball and flake powders are pretty much spot on, and stick powders are usually spot on with some being maybe 0.1 grains high or low. I weigh every charge no matter which powder or measure I use, and either trickle up or dump the excess in the trickler. The Hornady measure uses a large rotor for rifle charges and a small rotor for pistol, and I have found that when trying to throw small charges with the large rotor I get a lot of variation in charge weights.
FWIW, my father used Lee scoops when he reloaded some thirty or so years ago, and I shot plenty of his reloads back then with no issues. I recall him saying he used a dipper and leveled it with a business card, and any he checked on the scale were right there every time according to him. I never saw him reload, but his method worked and made good safe ammo.
There is more than one way to skin a cat, and I won't say that any one way is better than another. Find what works for you and run with it.
