Adobe Premiere Pro CS5.5 is hard to beat. However, with that said it really boils down to what you need to get your job done. For example, there is lots that can be down using a product like Corel Video Studio X4 and there are those that get by using it and actually making money with it however, if you are working on high end productions or have a format that cannot be read or converted (.mxf format) you need a higher end product like Adobe or Avid. For me, Adobe was more user friendly than what I found the Avid product to be.
