Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

LCD Screen Size and Features
Nikon S2900's 2.70" LCD screen is slightly larger than GoPro Hero9 Black's 2.27″ screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
