Scripts Vs Bullets and Notes?

When preparing to film your videos do you tend to have a whole pre-written script or find notes and bullets easier to use? I think for me it really depends on what I am recording. For something more serious I would be using a proper script but for my own content I find a few notes sellotaped around where I am recording to keep me on track really helps. Sometimes while recording I do wish I could easily look without needing to edit checking the notes out of the video
