Why do you say that Rails excels at templating? Ignoring for the moment the obvious differences between server-rendered HTML and JS frontends, the Rails templating doesn't strike me as one of the most prominent solutions Rails provides. The templating is fine, but other than a few niceties (like layout hierarchies and resource-based forms) it's not much more than a thin syntax to embed Ruby eval inside HTML.
If I had to pick the top things that Rails excels at, I'd point to ActiveModel and resourceful routing. I know REST isn't the hotness any more, but it sure is great for CRUD web sites or APIs, and Rails makes setting up database models, associations, and REST routes a breeze.
