I'd use the following metaphor to non-technical people. Rails is like a prepackaged toolkit, which can get most of the common tasks done fairly with ease. Whereas, node.js with whatever backend framekwork of choice, is like a DIY toolkit assembled by mix-and-match different tools in a large tool shop. Of course, at times DIY toolkit can do better on specific tasks. Given that you are the only dev on the project, I'd assume that the resource is fairly limited. And looks like you are not building some next-gen super duper fast smart application. So Just go with the prepackaged toolkit then. Rails is a very opinionated framework, there're pros and cons to it. But thanks to that, many of the gems are coded with it in mind. For example, they are all designed with same naming convention. Many will work well together out-of-box, for example devise and cancancan. Besides, many stuff are built in the framework. For example, logging utility, csrf protection, session encryption, etc. Yes, many of those stuff may not be useful or necessary at the beginning of the project life-cycle. However, down the road, there is a good chance you will need some of those. And the moment you realize that you already have it, it's so delightful. In addition, it's usually easier to debug a rails app than a node app in my experience. Personally, the cases where I would pick node.js over rails would be projects either require a) high-performance, or b) certain core functionality that has been implemented by some node packages but not by any ruby gems. In term of performance, node has a clear advantage over any other major web frameworks, except the ones built with go. It's simply a language feature. Node allows developer to easily write code that runs db query, external api calls, or other stuff of that nature in parallel. And that is THE MOST COMMON performance bottleneck of web applications.
