We started with c# decades ago, but lisp (and prolog by the way) kept nagging, so about 8-9 years ago I started getting my senior devs in workshops ; after about 6 months some of them asked wtf we are doing with that c# stuff?! While that is unfair, the debugging experience, stability, flexibility etc are more painful for my taste.
Also, the biggest complaint by many; I have not found any cases where packages we were missing in lisp but are there in nupkg or npm actually sped up any work in the long run. Our work is very regulated (so we check, read and fork the stuff we use to make sure nothing bad lands in prod) and our integrations almost never have integration packages available and if they have them, they are out of date or very badly done because everyone just does it from scratch to make sure.
Maybe we are weird and that is fine, but, if there is one thing; we iterate faster than our competitors.
