Besides vertex positions, it also stores surface normal plus a UV coordinate that can be mapped to an external texture.

OBJ as first created by Wavefront is a simple format storing vertex information to represent a 3D mesh.

It stores only geometry data and has a compact file size.

STL (STereoLithography) is a format originally developed for stereolithography 3D printing that is the most commonly accepted file format in 3D printing.

For exporting designs to a different format, Meshmixer also supports Collada, VRML, and Smesh. Meshmixer will read numerous 3D file types, such as STL, OBJ, PLY, and some lesser known formats AMF, 3MF, OFF, and the native MIX format.
