I would too, even though I've come to dislike mutability. Ruby has the community, the libraries, and the features. It's also a fairly consistent and clean language overall. I'd rank it at roughly the same level as Arc, maybe a tiny bit higher.
Ruby syntax is quite consistent and clean, and its support for closures very handy. I really like it.
Clojure has a strong philosophical bias for immutability and a functional approach, but has a slightly higher overhead with its combination of Lisp and support for Java. I think it has a bright future, despite pg's view that the jvm isn't what the 100 year language will be built on. :)
