How much experience do you have with each of the three? Like many, I moved to Elixir + Phoenix from Rails and having a considerable amount of experience with Node.

I've found Ecto to be a productivity boon once I understood it, except for very small projects. For those, I reach for Rails just as you suggested.

My real productivity boost with Phoenix is that Elixir (or the Erlang VM, to be accurate) can take care of so many things I'd be dishing off to Redis, Sidekiq or other tools in a Rails app. That and the lack of surprises from metaprogramming or ActiveRecord default behaviors I haven't kept in mind while building.
