CL is the most interactive (by far). Its image-based development and its tooling (Emacs&Slime or other IDEs) offer more features. Elixir's tooling is more classic, focused on good tools on the terminal. CL has a pretty good type inference, which happens interactively too (you can compile a function with a shortcut and have instant compiler feedback). Elixir people say that in practice pattern matching alleviates from type issues. It seems to me CL will have a wider range of applications (good for number crunching, different implementations); it's possible to build self-contained binaries in CL. CL isn't entirely functional, nor pure FP, you can mutate things (and can not to with some care, or with libraries) and you can mix styles (with OOP etc).
