using less stack

Is this generally considered good design?  That is, is it generally
preferred to express functions in a nonrecursive style if that can be done
using standard library functions like foldr and map and filter,
etc?  Okay, obviousloy everything *can* be done in that manner, so I guess
my question is why should we write something using foldr when, imo, the
explicitely recursive version is easier to parse (as a human).
