Well, a lot of coding comes down to data structures and algorithms, and I feel that Scala has the best out-of-the-box collections library experience of any language I've used. This makes it easy for me to choose an appropriate data structure and write my code as a series of transformations on it. I also like to think in terms of objects and Scala has the best fusion of OO and functional that I've ever seen. Finally, for most problems I like having a type system to help catch errors and to help shape the design process, and I like the IDE and tooling support that comes with it. That said, I've never written a line of F# and have written very little Haskell and Clojure. Clojure also seems like a fine language to get things done if it is more your cup of tea. If I were to pick a Lisp for development, Clojure would definitely be it.
