@Elenion As you say, I think it depends very much on what you're doing with the footage and whether you want to grade. Some like a desaturated cine mode, but unless you grade it, it looks terrible!
Nostalgic certainly gives you a lot of headroom for shadows and is generally less risky. Sometimes it is nice to have the footage 'pop' without grading though :)
My favourite one for quick shots with no after grading i like dynamic. I like nostalgic too for the dr. Many like smooth but i really can't hold it, i find it too washed-out
