I would pick Clojure over any statically typed FP language simply because it's far easier to train news devs for it. My team has been using it for close to a decade now, and we've only hired a single person who already knew Clojure during that time. All the other devs came from mainstream languages, and we were able to get them productive within a couple of weeks on average. There's simply no way I could teach a language like Haskell in a couple of weeks and get somebody reasonably productive with it. Monolithic design is not a good way to structure projects IMO. Any large project can, and should, be broken down into small isolated components that can be reasoned about independently. Not only does this reduce overall mental overhead of understanding the code, but it also makes it much easier to reuse. Static typing appears to encourage coupling via the types due to them having to be expressed globally. So, it naturally steers the design towards building a monolith. I also completely disagree that the REPL is some kind of a crutch. It's a strictly superior workflow because it allows you to put the application in a particular state, and then develop functionality against the state you've already built up. Having to restart the application, and rebuild that state every time you make a change is simply not a productive way to spend your time. Finally, the claim that Clojure hasn't found a niche is pretty weird seeing how it's used all over the place by companies big and small. It's certainly found a very nice niche in space of web development and companies like Apple, Atlassian, and Walmart are getting pretty good mileage from it.
