It's a trade-off, you trade certainty of types validated by the java compiler that comes with alot of ceremony with conciseness and agility provided by the repl, the downside being you need to ensure the result via tests and discipline. Source code quality and developer ergonomics are somewhat subjective, so its natural different people have different opinions. Personally, I quite like the clojure tradeoffs.
