I don't think we have a CGNS writer, but DMPlex can read it. Xdmf gives you a little more flexibility in choosing a schema for the HDF5 file, but you can put other stuff in CGNS files and Xdmf has its share of shortcomings. If you are happy with CGNS, I would say to use it and report any issues you have. We'll enhance the implementation so it can do everything you need.
