Recursion is a powerful, relatively low-level approach, and the price for expressive power is readability, but it has legit use cases. What you said has a grain of truth in that usually you should prefer combinators like map or filter (if you're doing FP), but just throwing away recursion is silly. Having a strong opinion on it and not seeming to know about TCO is also not a good look.

I don't think it's necessarily more difficult to read, especially with the mindset of the "recursion goblins" mentioned in another comment here, where one only looks at the current iteration and does not care about, where input argument comes from. But of course, if what one wants to do can be expressed using map and filter and such, why write some recursive procedure.
