I’m in the same boat and it actually is not true that these programs provide identical results. Through simply taking the same video file and adding the same LUT in Premiere and FCPX, there was a clear difference in the color of my clips. They’re not extremely different, but enough to notice there you won’t get two identical end results. For me, I can cut a lot faster in FCPX, but for coloring I’d rather work in Premiere.
