Quite honestly, I have not played very many of the famous early adventures (only D1 with EOTB at Gary Con, F'Chelrak's Tomb with austinjimm at NTRPG Con) and I have only read through or run a few, including B1, B2, T1, S1, S4, Caverns of Thracia, Necropolis. Part of me wants to read the rest, but another part keeps hoping I get a chance to play them someday. We'll see!
Of newer material, I've enjoyed adventures by James Boney (used White Dragon Run as the basis of a campaign), Guy Fullerton (Many Gates of the Gann), Matt Finch (Pod Caverns) and of course the Hyperborea adventures (Dunwich, Rats, Charnel Crypt, Ghost Ship, Comet and next week Forgotten Fane). There might be a few others.
