Having used “the big three” in anger, I would go with Baselight.
The colour science employed by the guys at FilmLight gives me what I expect time and again, with speed and accuracy.
The Blackboard control surface is the best and most comfortable I’ve used and having my layout mapped to my own specification saves a lot of time looking down and muscle memory.
Having said that, I will always have a soft spot for Nucoda Film Master as the DVO Toolset is second to none when it comes to restorative power. I also miss the Valhall panel, that thing was built of granite and you really knew when you pushed the buttons on it. Great bit of kit.
