Ya the malls in Dubai are better.  I mean come on, you can go scuba diving and skiing in them!  However, the sad thing is that in Dubai your life revolves around shopping and the malls, the great thing about Qatar is that your life doesn't have to revolve around a mall.  Go to Souk Waqif, The Pearl, The Cultural Village, the Museum of Islamic Art, the parks, the Corniche, etc.  These are all things that Dubai doesn't have!
