Been doing rails for 3 years and web dev for 8. Scaffold generators are terrible but model generators save time on boilerplate code and give me most of what I want. Test libraries can hook into this process as well saving further time. Rails has plenty of drawbacks but I see some of the CLI capabilities as a strength IMHO.
It's the model generators that especially give me pause. I like to noodle around with my fields before putting them in place. I love designing my models in code.
