Helpers are used inside templates. They're used when there's more ruby that you want to use than HTML. Partials are also used inside templates. They're used when there's more HTML that you want to use than ruby.
So, for example, text_area is a built in helper method because it takes parameters and spits out very customised HTML. Partials are usually used for sections of your web app interface you want to reuse on some pages... They'd look very ugly when written into a helper method. It's a matter of aesthetics.
