My Choice
If I were choosing between these two phones, I would pick the Oppo Reno6 5G. While the Samsung Galaxy S21 5G has a superior display, audio, and some camera features, the Oppo offers a better balance of performance and battery life at a potentially lower price. As a person who uses a smartphone frequently for various tasks throughout the day, the extended battery life and extremely fast charging are invaluable to me. Also, the Oppo has a versatile camera setup that is more useful for various situations when you aren't looking for pro level video features and manual camera features. The marginally better benchmark scores are a nice bonus but would not be a key factor. I would be happy to sacrifice the slightly better screen and audio features of the Samsung, for the longer lasting battery life and faster charging speeds that the Oppo offers. While the screen is good on both, the extra brightness offered by the S21 5G would rarely be utilized, whereas the extra battery of the Reno6 5G would be noticeable in the real world every day.
