Current data is always your best bet.
However, there are some editions of various manuals that are considered to be better than others, due to errors, cartridge selection, or the amount of data per cartridge.
Barnes #3 is better than Barnes #4
Hornady #6 and #7 are better than #8 (#9 has just been released, and I haven't made up my mind about it, yet)
Lyman 48th / 49th - depending on what you're after, the 48th might be better.
I know I'm forgetting at least one more....
