As a former "video editor", (that is how Design Dynamics got started), I have played on both sides of the fence (Mac and Windows). FCP was easy to get up and running. Vegas was too, but early days it was buggy. So I keep using Premeire. Pro tools, Avid even back in the day of the Toaster, when it dominated the scene, my favorite was Vegas. Open format, unlimited tracks, no matter the content, etc..
I have not edited a video since 2006. I still have all the software. Loaded Premiere the other day and it would not capture with the new computer hardware technology, oh well. Those days were a lot of fun.
