I think a lot of people feel that way, but it's a false dichotomy based on what I've seen. The more real choice is between Node/Ruby and just Node. When building a web application, you're basically forced to use JavaScript. It would be nice if this wasn't the case, and there are some transpilation tools that can basically get around that requirement, but it's almost always more painful to go that route. So if you're basically going to need the Node toolchain anyways for stuff like Babel and Webpack/Browserify, having your CSS abstraction library also use it means not needing an extra Ruby dependency. But there's not really an option to use only Ruby.
