I’m not sure if Finisher, Tonegrade or Skintone is better for my footage?

Finisher is designed for recovering detail while SkinTone recovers the color for different types of skintones. ToneGrade is a look, it will change your current coloring and make it into an HDR looking shot. Finisher and ToneGrade can work on any shot but SkinTone works with shots of people.
