* etsy/statsd is the official statsd implementation, yet hasn't been maintained for more than 2 years.
  (see also https://github.com/etsy/statsd/issues/649) 
* dozens of forks and re-implementations exist in the community.
  usually they bring one or more of extra features (e.g. graphite tags, security, ...),
  easier deployment and better performance,
  with various degrees of backwards compatibility

Which implementation is "best" depends on many factors, but often enough, it's not the official reference implementation.
IMHO, most of a statsd server's responsibility is catering to an organisations need of how they organize/name/.. their metrics.
So any implementation is very opinionated, and for etsy/statsd trying to cater to many different styles leads to a ballooning complexity
