You know, it's a personal choice and feeling. I know Ruby well, (bc I knew Perl very well) - but Rails 3 is just bulky and cumbersome. I felt like for the most part that I was wading through thick water every time we had to add more features. Granted, the Rails way I haven't agreed with, and we hated having to move from JS <--> Ruby/Rails or do the front end work in a clunky HAML/ERB view (we moved to using no views - just JSON API calls and rendering client side). We eventually found that the front end was JS & the back end ended up having to be python (for computationally heavy tasks). SO Rails just acted as the intermediary, which I felt was clunky. (Although I miss migrations in Sails JS). Does that help?
