Reading through http://www.enseignement.polytechnique.fr/informatique/INF562/Slides/MeshDataStructures.pdf, it seems like the halfedge mesh representation is well-suited to mesh representations with a variety of polygons. However, the triangle-neighbor representation also seems like it would be much simpler to perform some operations (including edgeFlip and splitFace, which have diagrams in the linked slides). Is this mesh representation sometimes used for triangle meshes?
