Some great suggestions here!
The Primeval Thule campaign setting and included/accompanying adventures are superb, especially if, like me, you are a fan of Sword & Sorcery and Weird Fantasy stories.
I'm a huge fan of the 2e Al-Qadim sourceboxes; all of them are super evocative and have great adventures in them (though many might be a challenge for modern DMs to run, just because the expectations of the game have changed so much).
Similarly, the Spelljammer stuff from back in the day was great - I miss the days of D&D not taking itself so damn seriously.
All of the 3.5 Eberron materials were amazing.
I'll cast another vote in favor of the Dragonlance Time of the Dragon/Taladas materials. Super well designed world and societies that have even greater depth if you are familiar with the more popular Ansalon oriented DL products.
When we're talking BAD modules, though, one I don't see lambasted enough is DL16: World of Krynn. The adventures in it run from bog standard to aggressively dull, with the occasional detour into asinine (did you know that Lord Soth, the world's most famous death knight, keeps the Tarrasque in a room of his castle? It's there in DL16!).
