Filters exist to process text that isn't Haml, and may obey other rules of indentation, etc. It's possible to implement a superset of the functionality of filters using helpers and the :plain filter (although obviously this requires at least the one filter to work), but that's just ugly.
In short, helpers should be used when doing something with Haml, and filters otherwise. Except filters can't dynamically access anything (nor can they take args, to answer your other question).
