Question Ranking
Pros
Pro Free tile-placement plugin
AutoTileSet is a tile placing tool part of the AutoTileGen family that is supported in Unity, Construct 2, and GameMaker to create tilemaps. AutoTileSet does not need AutoTileGen to work.
Pro Auto-creates tilesheets
Auto Gen Tile takes a few image parameters and a few settings that will quickly create a full tilesheet with 48 tiles for full bordered terrains.
Pro Auto-creates borders on tilemap
While placing tiles on the tilemap AutoTileSet will place appropriate borders and filler tiles instead of the user having to change each tile for each variation. It also support multiple tile sheets for variation and placing them correctly.
Pro Good documentation
The documentation for the toolkit is well written and there are video tutorials as well as an active community.
Pro Includes source code
No need to pay more to get access to the source code.
Pro Pixel-perfect camera
Pixel games in the style of 8 or 16 bit systems need to have each pixel uniform on the screen which 2D Toolkit supports with a camera component.
Pro Add colliders in the atlas editor
Choose from either a box, sphere, or mesh collider that will output as either a 3D or 2D collider in Unity.
Pro Create different resolutions of atlas
2D Toolkit allows for different sizes of atlas from 1x, 2x, or 4x which can be changed depending on platform resolution.
Pro Built to work inside Unity
2D Toolkit is an editor extension so users don’t have to leave the Unity engine for tile mapping.
Pro Create Atlases within the tool
Create sprite sheets for tiles to save draw calls and to keep tilesets organized.
Pro Supports the Tiled TMX Format
Create tilemaps in Tiled and implement with 2D Toolkit.
Cons
Con Extra work needed for Isometric Tiles
Isometric tiles are not technically supported but can be achieved with camera work and setting up tile art yourself.
Con Doesn't integrate with Unity's Sprite system
2D Toolkit provides a completely proprietary sprite implementation. Though it can be used alongside Unity's 2D systems, the two are completely separate and require different code to utilize.
