I'm sure there has been. I don't do video for a living, so my upgrades in camera, lighting, audio and post happen at a snail's pace as needed per project. So, @TomTheDP is partially correct in that RAW and ProRes are a lot easier on my computer, with ProRes being a native file in FCPX making my post processing very simple but I'm also a one-man-band shooter, so having the leeway to correct my mistakes while worrying about a dozen other things on set offers a huge appeal as well. But in the end, raw and ProRes both have a thicker image to my eyes and the motion cadence seem more cinematic to me.
