I've been using ReScript for a few months now. So far I mostly like it, but it takes some time to get used to it. The error messages can be confusing though so I try not to depend too much on type inference. The other downside is that some bindings for some of the web apis seem to be missing (like for the types in the Dom module).
Btw, for Material UI there are already bindings [1]
