I've never finished Castle Amber. The last time I ran it was as an on-the-fly conversion just after 3E came out. We got as far as the garden.Castle Amber (I have a vague feeling this is a great adventure)
ToEE (we did the first level but that was it)
I also have
Grakt's Crag
Halls of Tizun Thane
Pool of the Standing Stones
The Lichway
Maldred the Mighty
Some of those White Dwarf adventures are (in my view) a bit dated - Tizun Thane has some clever bits, but also some padding, and likewise the Lichway. I ran Maldred the Mighty once (maybe twice?), converted to Rolemaster. I don't have fond memories, but I probably didn't get the best out of it.
I used this as the basis for my 4e campaign, mixing in other bits and pieces (Thunderspire Labyrinth, Speaker in Dreams, Heathen, plus some stuff of my own design).My favorite module is B-10 Night's Dark Terror:

While the introduction is a little weak, the rest is great, featuring overland travel, exploration of old ruins and the discovery of a forgotten civilization.
But I don't agree that the introduction is weak - if you mean the "defend the homestead" bit, that was great!
I recently ran G2 converted for a mid-Epic 4e game - links here and here. Of the G modules I've always had the fondest memories of it (mostly because of PCs falling over the edge into the rift), and it didn't disappoint.
It's probably 20 years since I last ran D1, but I have fond memories. And I ran D2 in my 4e game about a year ago: link here.
