I work in a large Sorbet codebase (though it isn't a Rails one) and it's a huge boon IMO. The number of tests we don't need to write because of Sorbet is really nice.
It does occasionally require structuring your code differently, but I find the type-system-encouraged approach often gives a more elegant and harder-to-misuse interface in the end.
