node-statsd[1] hasn't seen any maintenance in a little over 4 years at this point, and hasn't seen any real responses to Issues or Pull Requests during that time.

In the interim, hot-shots[2] forked off from node-statsd and has been consistently maintained and extended to support statsd-like offerings from Datadog and Telegraf.

I'm not saying that node-statsd isn't working (it is), however hot-shots has maintained API compatibility with node-statsd and offers users more features and options, and a greater likelihood of any bugs that may arise being fixed in a more timely manner.
