re: Arnold vs Stallone. Which has the better filmography/catalog.

I am going to answer it this way: If one or the other had never been born, whose contributions to the film industry would have been missed the most?

I say Stallone. There is no Rocky Balboa (period) without Stallone and that’s a pretty damn big blow to the film industry. Maybe someone else would have been great as Rambo or the T-800 or other great roles of Stallone and Arnold but I favor Stallone for his writing and directing.
