If you think of ReasonML as a separate language (as I find it all too often is described), then it doesn't provide any extra value. However, as someone who is a contributor to Revery, a fairly large Reason project, the benefits of using Reason over OCaml are:

- JSX. OCaml has infamously never had a great UI lib, even though the language parallels with many of the functional paradigms popularized by React. JSX is a great medium to bridge that gap.

- The syntax itself. A lot of the contributors to Revery have no OCaml background, but rather JS since it's often billed as an Electron alternative. Reason's familiar syntax opens the door to many people who would be turned off by OCaml's "obscure" (not my actual thoughts) syntax.

- The tooling. Since it's just an alternative syntax for OCaml, you get all the OCaml tooling for free, plus the Reason-specific tooling. I'm a huge fan of refmt, which is a tool that parses and formats Reason source files. Sure other langs have close-ish equivalents (i.e. clang-format), but refmt is much more opinionated, meaning you never have to worry about intricacies with your formatting.
