I'm a long time ruby developer and have switched to erlang/elixir now for about 2 years now. IMHO phoenix is at least as good as rails, personally I think its most often a better option when building large applications, though this is due mainly to elixir/erlang and OTP. Elixir offers production grade options for all the major packages/libs you need and all the packages I've had to build have been the same kinds of minor things like api clients or whatever that I had to build a gem for when I was using ruby. So phoenix/elixir is certainly a "real alternative" since I've been building production systems in it for 2 years. lastly Phoenix is not quite as opinionated as rails, but its still very opinionated and any rails developer will feel very much at home there.
