If you prioritize a top-tier camera and are particularly interested in telephoto capabilities, the Samsung Galaxy S21 Ultra, being less expensive, offers excellent versatility including a 10x optical zoom. However, if you prefer longer battery life and a slightly larger screen with a more recent release date, the OnePlus 12R may be worth the extra cost. Both phones run on Android, have similar storage capacities, and offer 120Hz refresh rate displays, while the OnePlus 12R has a higher peak brightness which could be beneficial if you're often in bright environments.
