Pros
Pro idTech1 and Build engine voxel editor
While the idTech engine 1 (aka the "DooM Engine") does not support voxels, newer limit-breaking source ports have added the ability to render the .kvx voxel format designed for the Build Engine. Slab6 is currently the only well-known .kvx editor as it continues to pop up in DooM modding forums and tutorials. Even though it's not the most user-friendly editor, its support for .vox export enables the model to be edited in MagicaVoxel or voxels made in MagicaVoxel (which supports Slab6 (Slab) .vox export) to be converted to .kvx for use in-game.
Pro Cross-platform
VoxelShop is available for Windows, OS X and Linux.
Pro Free
VoxelShop is Open Source. You can download and use the software for free, but donations are encouraged to support the project.
Pro Great for game-dev
Exported .dae files are optimized to lowest possible amount of polygons. Despite lack of animation support .dae files can be imported to Blender and animated.
Pro Layers
Pro Export to COLLADA
Pro Exports optimized meshes
The export (to DAE files) removes unnecessary geometry, creating an optimized model.
Pro Palettes
Easy to go with a theme.
Pro Textured voxels
Pro Exports to kv6
Helpful for making larger voxels for Doom.
Cons
Con Not very user friendly
If I asked most people to use this to draw something without reading anything about the program, a good percent would not be able to. with odd controls like 'Insert' to draw, 'L' to open, and no customization on these controls, its requires users to read how to use it. the help guide only gives you a basic understanding of how things work and requires you to search through files in order to fully understand how powerful this tool really is. If i were to rate this for how user friendly it is on a 1 -10 scale (with 1 being like binary switch panels, 3 being ms-dos, 5 being a minimal gui with a complex console command line for all functions, 8 being able to sit down and perform basic operations, and ten being no effort at all,) I would give this a 7(has a gui that is easier to navigate but even simple functions require a bit of reading).
Con Website is no longer available.
Con Does not support .obj export format
Con Really buggy
Sometimes it crashes at startup, some large models instantly crash the program, having the mirror function on causes every action to get mirrored (even imports get mirrored).
