I am a fan of Christophe Grand's xforms library -- https://github.com/cgrand/xforms -- I find the transducer nexus function, by-key, to be particularly useful for eliminating clojure.core destructuring dances when one needs group-by with post-processing.

* It's fast enough for 99% of apps out of the box. It's fast enough for 99.99% of the apps with minimal tuning. * Yes, if your project is very big and macro heavy, it can take some time, but startup times have improved. In any case, I BARELY need to restart my development JVM. I have one currently running that I haven't restarted for 1 week+. * Depending on what's your cup of tea, there's emacs/CIDER or IntelliJ/Cursive. They both work well. IntelliJ/Cursive is an excellent IDE combination. I use it every day. * Java interop is very straightforward, not sure what you mean. Sure your code might not be all pure anymore, but that's the price for solving actual problems. * Good java libraries have wrappers. A ton of original Clojure libraries as well. https://github.com/cgrand/xforms for example allows you to easily do things that I can't eve

n imagine doing in an imperative language. * Static vs dynamic typing: don't want to get into that. * "Clojurescript isn't the same language". I use both Clojure and ClojureScript every day and as far as Clojure-only code is concerned, it works in both languages 99.99% of the time. One case you can encounter issues is if you do something host-specific, like dealing with numbers. That's by design. Clojure embraces each host, does not try to reinvent it. When you just use pure Clojure data structure manipulation, it works the same across both languages and works like magic.
