I always thought that the surrounding tooling (having to learn how to edit parens productively, using nrepl/cider, maybe even emacs... with evil-mode of course) to be both the worst and then eventually the best parts of Clojure.
For those six years I don't think I used emacs keybindings during that time except to move between files and execute clojure code. I couldn't be arsed to learn it. It was basically a fancier vim, haha.
These days I use VSCode for all software. At some point in my 20s I found out there's life outside of coding so now I use a less esoteric editor. I'm sure its clojure / nrepl / paredit / parinfer support is fine. (Seems to be this: https://calva.io/) Back in 2010 the options weren't as great.
