My team has a large ocaml codebase and a dual build system (buck2 and dune). The two have roughly similar: dune faster at the raw speed of invoking ocaml build tools, buck2 winning out when a lot of stuff has to be rebuilt and it uses distributed build system.

The major pain point is LSP integration, which has to be closely tied to the build system, since it's only by building that the LSP server can know a file's dependencies. Everything is all neatly available with dune. We've cobbled something together a bit with buck2 but it's not as nice.
