Rails is an awesome framework to develop in. For me, however, it is less about Rails and more about the community. Take for instance the popular Ruby job processing system, Sidekiq. It integrates very easily into Rails and makes that whole async job thing painless. I haven't seen anything as sophisticated in other languages. ActiveModel is also a very nice library to work in, and having it by default is nice. I personally do Rails backend + Angular frontend and it is a very rewarding stack. I get the power of Angular, but the simplicity of Rails in the backend. DHH is wholly against that, but it works really well.
