So what's the difference between voxels and 3D models?
I sort of understand, but not really. Is one easier to work with?

A 3d model is a set of points in 3d space (vertexes) with lines in between. The lines form surfaces, giving shape to the model. Then, an image (texture) is "painted" on the faces of the model to give it a "skin."
A voxel is like a traditional digital image in 3 dimensions instead of two. Picture a Rubik's Cube; It's a 3d object made of a bunch of little cubes in the same way that a digital picture is a 2d object made up of a bunch of little squares (pixels).
Note: the word "voxel" is analogous to the word "pixel;" one voxel is a tiny part of what would make up a "voxel image." However it seems that the word is used to mean both the small voxel unit and the whole voxel image.
