Meteor lets you do a lot, very fast. The result is not as lightweight as a pure backend app sprinkled with JS, but it makes sense for the heaviest uis of your app. I use meteor for the backend of the app, where farmers list their products, clients, etc .. The data is allways up to date (real time data sync) and the UI is derived from that data, which makes state management very easy.
Express and other backend only frameworks are great for making lightweight, accessible and fast pages. I use it for the public facing forms, which are seen by ~100 times more people. They are basic, fast, light, and work without JS and on shaky connection. The client side interactions are coded in vanilla js, transpiled by babel.
