Would you rather get one AI-probability number, or the reasons?

We launch PEA on Oct 17. Before that, a question for anyone who has used AI image detectors.

Most tools give one number ("87% AI"). PEA lists what it confirmed and what raised concern instead, and refuses to grade images it can't judge, like a still from a video or a photo of a screen.

Which would you trust more, and what would you actually check with a tool like this?
