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

Arnold's high was higher and arguably lasted longer than Stallone's high.

Peak Arnold was say 1982 Conan until 1994 True Lies, so 12 years. The summit of his high was T2 (with notable false summit Predator). Pretty remarkable stretch. But post 1994 it gets really dicey. Eraser 1996 was ok. End of Days 99 was ok. The Expendables movies are decent enough, but Sly is in those too, so they dont count. Really 1994 was about it for truly great Arnold movies.

Peak Stallone was 1976 Rocky through 1985 Rocky 4 or maybe 1988 Rambo 3, so either 9 years or MAYBE 12 years if you stretch it. Nothing in that stretch reaches T2 or Predator level in my opinion.

BUT

post 1988 Rambo 3 you still have SO MANY bangers. Cliffhanger 1993, Demolition Man same year, Judge Dredd 1995, Cop Land 1997, Rocky Balboa 2006, Rambo 2008, Creed 2015, Creed 2 2018, I'll even throw in Last Blood because I liked it alot.

I think overall career HAS to go to Sly.
