"I don't feel like I'm having a "far better" programming experience with Clojure than with C#. The language is somewhat better, but the tooling is somewhat worse, in my opinion."

That does make sense. When it comes to things like, say, desktop application development, Clojure probably isn't there yet, even though it's backed by all the Java libraries. C# and .NET, on the other hand, were designed with this purpose in mind (among other things). If I had to write a Windows desktop app, I probably would choose C# over Clojure any day, even though I like Clojure better as a language. But, as they say, programming languages don't operate in a vacuum...
