We present SEDs for Cen A, NGC 4151, 3C273 and 3C279 with new results from the CGRO. The spectra cover 16 orders of magnitude in v, radio to γ-ray, over 20 years of observations. These 4 galaxies represent a Seyfert, a FSRG and 2 blazars. The γ-ray data indicate two classes of AGN. At γ-ray energies Type 1 Seyferts and radio galaxies have quantitatively different properties from blazars.
