This is a great question. I do not know which is best, but would like the information as well. I have been doing a comparison of the various programs available and have found some features that I really like. Some of these features are: PanVue and Arc panoramic maker. Both of these programs allow you to stitch images together. I have heard that Arc's software program make the graphic very seamless, which is important because I do not always have the proper lense but what the panoramic view.
