What I Would Choose and Why

If I were choosing between these two phones, I would pick the Samsung Galaxy S21 Ultra 5G. My reasoning is based on the fact that I prioritize performance, display quality, and camera capabilities over a slightly lighter build and newer software (as the S21 Ultra will still receive many updates.) The S21 Ultra provides an overall better user experience, especially for tasks that require more processing power and a better display. The significantly better camera system and its additional features are also a huge plus for me. Even though it is an older phone, the S21 Ultra still holds its ground and would be my daily driver.

However, for a user with a tighter budget, who doesn't need all the bells and whistles, the A35 would be a very good option.
