One of the arguments is how noisy the languages are. Elixir is without a doubt more powerful, more scalable and more sophisticated than Ruby.

What Ruby has though is ability to express what you are doing in a clear syntax. Elixir has a lot of ritual (albeit less than erlang) to set up your most used things like GenServer - you don't abstract away the concurrent flow (which is good, concurrency should be obvious), but you also wouldn't write elixir without it, so code inevitably becomes filled with technical concerns.

I'm biased, I write elixir for a living after a decade in Ruby, and I'm happy with that tradeoff. But there are times where you need to do an imperative thing and make it clear as day, and Ruby often does a better job here.

Rails is also somewhat more ergonomic for fast prototyping than phoenix. ActiveRecord is a blessing and curse, it's insanely productive for making things do things in minutes, but lacks composition later on.
