I’m a Premiere user who has never used Final Cut, so I can’t speak to the technical differences. However, it seems that there is really only one question you have to ask yourself… well, how did I get here? Wait, that’s not it. Do you get the results you want using Premiere Pro? If so, who cares what others think.
The only possible downside I see is if Final Cut is the new standard out there. It may be harder to find work with experience on Premiere Pro rather than Final Cut Pro. I’d be interested to know if that’s true.
