I too like the Lyman handbooks. Primarily because they are not in the business of selling either powder or jacketed bullets, so have no particular ox in the show, so to speak, and use all suitable bullets and powders in their data. Then, of course, the fact that they do publish cast-bullet data for the majority of rounds is also of great value. In addition, they give information for a lot of great, old obsolete cartridges too, which I like because of my interest in the old ones......
