Perhaps its easier for you to read. It takes me 2-3 longer to read the loops since each loop is unique and I have to parse the semantics/context, whereas its quick for me to parse the behavior from the named functional operators even at a glance. Conversely I find writing the functional version a bit trickier for complex reduce operations.
