I don't think worse is better applies here. There's also JRuby and rubinius is in a weird limbo state where it's not quite Ruby like JRuby and it's not quite another language like Elixir. Similar thing happened to Dart I think. It was stuck in limbo and never got adoption. So between JRuby and Rubinius I choose JRuby because I've used it in the past and it's great. The fact that JRuby folks try super hard to maintain compatibility is also really nice. I want to know who is actually using Rubinius and in what capacity and why.
