One strong point for productivity/getting stuff done fast in real world: good REPL. It's not just Rails of course, but worth noting when comparing interpreted languages to compiled ones. Rails console is not only a great development tool, it's also an invaluable way to tackle customer support problems quickly.

There are several reasons I've come to prefer phoenix over rails but a big one is definitely the experience of using livebook with it. The first time I saw someone use that to simultaneously diagnose and document an incident just blew my mind. Now a few years in it's one of the few things in programming that ever really lived up to my expectations lol.
