Ramses II achieved the status of 'greatest Pharaoh ever' on account of his long, successful reign, but mainly his unequaled monument building program throughout Egypt, shamelessly faking military success, notably in the battle of Kadesh against Egypt's Hettite challenger for dominance in the Middle East. His vast, rock-carved double temple at Abu Simble, deep south, is formally dedicated mainly to the sun god Ra, but actually the culmination to raise his status from gods' favorite to one on earth. It's also a spectacular feat of architecture and logistics, rivaled only by his super-size temple for his cult at the capital Luxor, with granaries as treasury for the adjoining administrative school. Relarkably, his queen Nefertite gets unparalleled status, as his joint high priestess and deputy in state matters, equal-size at her own Abu Simble temple, because he was of commoner officer stock, hence needed her well-advertised noble blood to justify his dynasty's claim to the sacred throne.
