Working with Phoenix, and even more so Elixir and OTP, has been a great joy at a similar to almost the same level I had when transitioning from DotNet to Ruby in 2010 for my experience.

There are still some rough edges, and the job market might be more challenging, but overall I feel anything Elixir related at the moment provides for a high quality filter - both in terms of job opportunities and teams as well as the general product development experience.
