The iPad Pro 13 Inch M4 wins due to its tandem OLED display delivering 1000 nits full-screen brightness and 0.2-inch thinness versus the Air's LCD at 0.24 inches (per Apple and RTINGS). The Air provides strong value with the same M4 chip for 128GB starting storage at a lower price point. Pro excels for creative professionals needing the superior screen and Thunderbolt connectivity.
