If camera quality is a priority for you, the Samsung Galaxy S21 Ultra offers better overall camera performance including photo and video quality. It also has a larger screen with a higher resolution, which could be better for viewing media, but makes the phone larger and potentially harder to handle. The S21 Ultra includes a glass back, which may feel more premium than the plastic back of the Zenfone 9. The Zenfone 9 is priced higher, but has a smaller screen which could be preferable if you're looking for a compact phone. It also has a fairly robust battery life and includes a headphone jack, which the S21 Ultra lacks. Both phones are Android devices, with the Asus offering a slightly longer warranty period.
