Simplicity is the big draw. It's a lot easier to just pick up and play. Only familiar with one of the games you listed, but compared to, say, Descent, it takes a fraction of the time to learn or set up.
The Quest Book has a lot of really fun scenarios that use the simple ruleset to create dungeons of surprising variety. Particular shoutouts go to Melar's Maze and Castle of Mystery. The expansions, particularly Return of the Witch Lord, go even crazier with expanded options and neat twists on the basic formula.
The art style of the classic game (which I do not in fact own) is very neat from what I can see.
