Best: Ghosts of Saltmarsh. Ghosts of Saltmarsh is the perfect format for a 5E book. It introduces a setting to play in (complete with factions, roll tables, and maps), 7 adventures that can be used as one-shots or to make a campaign (with guidelines to do both), new character options, new magic items, new monsters, and best of all, thematic rule supplements to the core game. Overall a very well designed book.
Worst: PHB. Honestly, the book has sold well off of name alone. Why I put it worst, though, is because the organization of the PHB is honestly freaking horrendous. It isn't clear in what it communicates, is confusing to navigate, has a horrendous index, and overall needs a lot of time with to fully grok. Not very friendly to newbies at all.
Actual Worst: Monster Manual. For the reasons above + the fact that more interesting monsters are contained in other books. The basics coulda' all been put in something else IMO.
