I don't know what you intend to use for creating comics, but I like Comic Life.  The auto text bubble feature is an incredible time saver.  It allows you to save to various formats.  I usually save to JPG, then import the JPG's as images to a word doc (one step - incredibly fast if you set up the pages), then export as PDF.  Works like a charm.
