Being the GOAT is subjective, it's not just about dry statistics. I'd argue the cultural impact of Diego Maradona was incredidibly more profound than Messi's, ironically much due to his turbulent life off the pitch. People like an anti-hero :)

The 1986 world cup was incredible, the impact of that WC run on the Argentinian national psyche, including the final but especially the Argentina–England game, just cannot be overstated.
