My Choice
If I were choosing between these two phones, I would choose the Samsung Galaxy S21 Ultra 5G. The primary reason for this is because as a smartphone analyst who is also a tech enthusiast I do require top performance and features for daily use, such as editing photos on my phone, playing games, or even editing videos on the go. While the price is higher, the significantly better performance, vastly superior display, excellent camera system, and better overall user experience make it a worthwhile investment for my personal needs.
While I understand that the Xiaomi Redmi Note 11 is a great device for the price, and it does offer some advantages such as a lighter form factor, I simply would never use that device when the S21 Ultra provides far greater benefits for my own personal needs. The difference between the camera and overall processing power is simply far too great to ignore.
