I know that and it's been posted often enough. However, the rails approach is fundamentally different from the padrino approach: Rails is very opinionated about which component should be used - as DHH stresses in his blog post. Padrino asks you when you generate your project. Both approaches have their advantages and disadvantages.
Changing the defaults takes 2 minutes in Rails. What's the problem? Besides, there are gems like Rails Composer [1], which allow you to create new projects based on a template.
You can tell Padrino what you want during the creation of a new project.
You can tell Rails what you want immediately after the creation of a new project. Rails simply saves you time by having sane defaults. Convention over configuration at its best.
Padrinos fundamental philosophy is to be a framework built up of independent components and with limited opinions. Rails is by default opinionated: You can swap out certain components but all in all you're expected to do stuff "The Rails Way". That's the difference. It may or may not matter to you and in many ways produce the same end results, but the approach still differs.
