Switch from Tasty + Hspec to Tasty + Hunit or just Hspec?

We use Test.Tasty.Hspec + tasty-discover, but with new changes to Test.Tasty.Hspec, they seem to discourage using tasty + hspec together and suggest we use just one.

So should we switch to Tasty + Hunit then? Or just HSpec? We should research this and make a decision.
