A couple of years ago I decided it would be good for me to get Apple Pro Certified on FCP. The majority of the job postings I saw were for FCP editors. I had never touched it before, but I spent a week learning it and got my certification. I put it on my resume and shortly thereafter got a gig subbing for a FCP editor at an ad agency. A few months later they switched over to Matrox Axio systems running Premiere. I had cut a few things on Premiere, so the transition wasn’t bad. I’m still freelancing there to this day. I guess my point is that anything that gives you options is good. I’m running a Mac Pro with both Premiere and FCP, so I can go whichever way the wind blows.
