Even though both of them are in the same family they could not be further away from each other. OCaml has many standard libraries more you can read here: https://discuss.ocaml.org/t/what-is-the-preferable-solution-for-the-role-of-standard-library/1092 https://discuss.ocaml.org/t/what-is-the-preferable-solution-... F# has (almost) everything that is available in the CLR, which means tons of high quality libraries, ready to be used in production. Another advantage is AWS support. Since C# is a tier one language in the cloud F# is also a tier one language. I am not sure where OCaml falls into in this space. Other than these I am not sure why, but these are pretty big ones for us. I love OCaml and trying to use it whenever I can, which is not that much unfortunately.
