My favorite features of Erlang/OTP in descending order:

1. built-in distribution (i.e. Erlang distributed RPC)

2. bit-syntax

3. light-weight processes

4. pattern-matching

2 combined with 4 is a secret weapon when parsing record-oriented files from old mainframes or minicomputers. Replace 500 lines of Java with one--very long--line of Erlang.
