I spent a lot of time on Standard ML in university.

OCaml was always portrayed as the engineer's alternative for real applications.

I spent some time brushing up on OCaml a few years ago using Exercism.io.

While OCaml is a personal "top tier" language, I'd always prefer Haskell, Rust or Scala.

Type classes / traits just seem to beat a higher-order module system for me.
