I think Haskell tooling is pretty good now. VSCode with the Haskell plugins is simple to setup. I used to use Emacs for Haskell, but the VSCode support is now so good that I just take the easy route.

Stack and stackage made package management much easier for me. I am an enthusiastic, but not great Haskell programmer so I like running the ‘hlint’ linter program for hints on improving my code.

My heart is really with Common Lisp, but Haskell is also a pleasure to use and the tooling seems much better to me than five years ago.
