Functional libraries in JS including the ones you mentioned add friction (syntax, dependencies etc.), performance issues and mental overhead. Clojure/Script is designed to be almost completely functional. The code you write is cleaner, more concise and performant almost by default. You also get one syntax to rule the whole web frontend system (js, css, html). For me the reasons for not using it as a primary replacement are: I get dizzy from interop; it is much more convenient to embed Clojurescript into JS than the other way around. And secondly and more importantly I cannot use it in collaboration.
