There are always Efene and Reia if you want sexy things. (However, I find it somehow disturbing that there are almost no documentation on Reia beyond the examples on its site's start page.)
One could compare Node.js to Twisted, Tornado or EventMachine. However, comparing Erlang to Node.js is somehow weird as they have different paradigms — Erlang is highly-concurrent with its "green" processes, while Node is single-process single-thread with "asynchronous" paradigm.
(However, there are some aspects, that could be compared. Erlang has "let it crash" motto, while in Node.js one has to be careful with any exceptions. Erlang is distributed and Node.js has no notion of processes.)
