The JVM is a great kitchen sink environment. The BEAM and Erlang/Elixir are much more finely tuned for their strengths: distributed systems, fault tolerance, immutable data/functional programming.
If you need raw performance, the JVM is definitely better. If you don't want to have to deal with the inherent tension between a FP language and mutable surroundings, the BEAM is worth a look.
