Leaving the fact aside that a prime lens usually exhibits better bokeh than a zoom, a lens with max aperture of 2.8 will not necessarily show *better* bokeh than a lens with max aperture of 5.6. It can, however, exhibit *more*, by virtue of the fact that there will be more areas which are out of focus. The term "bokeh" refers to the *quality* of out-of-focus portions of a shot: not the amount. Technically, you cannot talk about "more bokeh" any more than you can talk about one apple having "more shape" than another: Just focus so that nothing is sharp, and it's all bokeh.
