I personally find OCaml more pragmatic than Haskell.
Haskell has a steeper learning curve IMHO: monads are pervasive and are hard to understand, laziness isn't a common programming pattern and it adds complexity. I find type classes confusing as well, it's not always clear where things are defined.
I like that OCaml is close to the hardware, there are no complex abstractions. The module system makes it easy to program in the large (I love mli). If you avoid the more advanced features, it's a super simple language.
I should have specified. I wasn't asking about OCaml vs Haskell in general[0], but what advantage does OCaml have with respect to concurrency?
[0] I think most people just end up post-rationalizing whatever choice they have already invested in, I know I do :) With that in mind, maybe I as a mainly-Haskell dev should instead list some things I miss from OCaml: faster compile times, non-recursive `let` by default, polymorphic variants, labeled arguments
