I still use Leiningen since it covers practically all of my needs, including the needs of the teams in the past two businesses I've worked for. The Slack group has pretty vocal people pushing for deps.edn. It's a bit amusing seeing people slowly build their own Leiningen out of ad-hoc Makefile^W^W Babashka scripts and copy-pasting build.clj files across their projects. (Not to mention, nobody can remember what the -X, -A, -T, ... flags do, so that is a major reason Makefiles or Babashka scripts are commonplace in projects that don't use Leiningen)
If you're familiar with Java, then you can think of Clojure today as going through its Apache Ant phase. Some people love it, some people hate it. I personally want to spend 0% of my time building build tools; thankfully there is a pretty solid build tool that is still maintained and will continue to work for the foreseeable future.
