Which Inception clues most strongly argue Cobb is real or dreaming?

[RyanAP]

I just rewatched Inception for probably the fifth time, and I'm still wrestling with the film's final moments and the ambiguous status of the spinning top. While I understand the intentional ambiguity, I'm more interested in dissecting the specific visual and auditory clues Nolan provides throughout the film that might point to one interpretation over another, like the use of the children's clothing or Cobb's wedding ring. For fans who have deep-dived into the theories, what do you believe is the most compelling evidence, drawn directly from the film's own internal logic and repeated motifs, that suggests whether Cobb is finally back in reality or still trapped in a dream at the end, and does the top even matter if he's chosen to accept his new reality regardless?
