My Choice

I would choose the OnePlus Nord 3. While the Samsung Galaxy S21 Ultra 5G is undoubtedly a premium device with a fantastic camera system and display, the OnePlus Nord 3 offers a better balance for my personal priorities. The significantly faster charging speed and newer chipset are very important for my daily usage, as I want my phone to be responsive and ready to go at any time, without being tied down with slow charging. Additionally, I value the lighter and more compact design for daily comfort.

While the camera system on the S21 Ultra is superior, the camera on the Nord 3 still produces very good photos and is more versatile in terms of its additional wide angle and macro capabilities. Also, the newer Android operating system will mean it will be supported for longer. For me, the Nord 3’s focus on speed and modern software, combined with its value-oriented price, makes it the better choice, even though it does make sacrifices in screen and camera quality.
