I love both languages, but I don't see the tooling in one as vastly superior to the other. Elixir certainly has Clojure completely licked in terms of compile times; also the Mix command-line workflow is just simpler (no messing around with project.clj vs profiles.clj vs ~/.lein/profiles.clj and god knows where else).
On the other hand, Clojure REPL workflow (although some assembly is required) is phenomenal. Clojurescript is a serious option on the client. And for runtime-level tools (profilers etc), you have the whole Java/JVM ecosystem, which is simply bigger, for better or worse, than the Erlang equivalent.
So for my money, it's definitely a two horse race.
