I went kicking and screaming to Apple and Final cut in 2009 but never looked back once I was up to speed. While the learning curve was much steeper with Final Cut 7, learning it really paid off in a number of areas and the power of the Final Cut workflow became almost immediately apparent. The thing that I really didn't like about it though, was the need to transcode everything to ProRes before you could import it into the timeline.
Sony Vegas didn't require source media transcoding - it would take literally anything and allow you to drop it directly into a timeline and start cutting.
