To enhance the Generators Guide to Dungeons I've taken a look at the map generators around.
Map generators for Rooms and Corridors, Caverns, Mixed Caverns & Rooms, Maps with Descriptions and Pdf Options.

Rooms and Corridors
Gozzys does a dungeon generator map creator with wandering line style (pictured below) and random room style.
A similar style can be found at Dungeons Tome, with the Random Dungeon Generator. Mine has several false doors.
Myth Weavers has a cave generator.
Gozzys has the Random cave map creator with lots of options to tamper with.
Last is a slightly different style from NPC Base Cave Generator.
Mixed Caverns and Rooms
Dave's Mapper can do mixed caves and dungeons, as well as each on their own.
Dungeons with Descriptions
Donjon has several dungeon generators and the one for 5E has dungeon overview, a corridor key, wandering monsters and room descriptions. Other versions with description include Pathfinder, d20 and AD&D. All of them contain many options for customising the layout and its contents.
Myth Weavers does a Dungeon Generator with room details and monsters for Dungeons and Dragons 3.5
Dizzy Dragon Games has an Adventure Generator with gives a descriptions, treasure and encounters with old school monsters.
Rounding out the digital maps are a couple paid for options in pdf form.
The Dungeon Builder's Deck that provides 114 playing-card sized dungeon tiles
Dungeon Tiles: DM Essentials is a collection of dungeon tiles with rooms, halls and connectors that can be used on virtual tabletops.
