About "advantages vs. disadvantages"  the existing splitted (harsh ?) approach allows to analyse (and correct) each point clearly. What we are doing. In a second step, when every item is ok, I agree a more textual (paragraph) presentation is smarter. But not easy to write without a lot of "although, however", and long multi level sentences. 
 Last point, variations/examples would and will be nice (asking for quotes, too). The very object of the article.
