The iPad Pro 13-inch M4 wins decisively with its tandem OLED display (per RTINGS contrast measurements), faster M4 chip (up to 1.5x GPU in Metal benchmarks from Apple's specs), and thinner design. The M2 model trails in display uniformity and future-proofing but remains capable for everyday use. M4 is the clear upgrade for professionals needing top-tier visuals and performance.
