pygmsh is a convenience wrapper around the Python API of GMSH, and offers a subset of the commands in the Gmsh Python api. Historically pygmsh has had a "neater" interface than the GMSH Python api (thus its popularity). Personally, I use the GMSH Python API, as the user interface is stable, and allows me to do anything that is part of GMSH.
