An interesting comparison.

TL;DR: Elixir/Phoenix is worth a try :)

Sure, I tested it and I really liked it :D

Unfortunately, we have a learning curve to “master” it, and crystal has a smaller learning curve if you are a rubist (my case).

I’m studying more Crystal then Elixir just because the difference is not too big and compiling and sharing the binary is a great feature :)
