deps-new includes the same app and lib templates that clj-new has. deps-new does not run lein new (or boot-new or clj-new) templates -- you'll continue to need clj-new (or lein new!) for those.

Although deps-new has a pom shortcut, for creating a fully-fleshed out pom.xml, it does not sync dependencies -- you'll still need clojure -Spom for that -- but see also clojure.tools.build.api/write-pom which can sync dependencies, as well as fill out scm information now (although it's still more work than deps-new's pom 🙂 )
