Here's how they stack up (just added both of them to the list of languages and reran it):
By number of stories: 13. Julia (35 stories), 18. OCaml (13 stories)
By number of comments: 9. Julia (498 comments), 19. OCaml (82 comments)
By points: 9. Julia (1542 points), 15. OCaml (503 points)
I link to the Python script I used to generate this, so if you want to experiment with different date range or other languages/search terms, feel free to explore! (I do think Algolia API has some limits on the number of results tho so might not work out of the box for much longer time periods)
