Neither sound great for your proposed project. If you are stuck on that type of project, look at something like Griffon instead.

Otherwise, if you are more interested in expanding your mind and thinking differently, Clojure for sure. Scala is nice and a great Java replacement language, but it is quite a bit like Java and looks like Java and can be programmed like Java.

Clojure is different. Clojure is lisp but if it was written today instead of 50 years ago. Clojure is as close to pure CS as we have today on a modern platform.

I encourage every developer to learn a Lisp at somepoint, but today there is no excuse not to as Clojure works on the JVM so easily. Clojure will change your way of thinking and get you exposed to functional programming (FP) and that is a great thing!
