Scenario 3: Photography Enthusiast on a Budget: If you are a photography enthusiast, the Samsung Galaxy S21 Ultra 5G is a much better choice as it features high resolution sensors, optical zoom, and generally higher quality output.

My Choice
I would choose the Samsung Galaxy S21 Ultra 5G. While the Motorola G53 offers a more modern Android OS out of the box and is lighter, the S21 Ultra's superior display, significantly more powerful chipset, and vastly better camera system outweigh the downsides for me. I frequently use my phone for photography, video content consumption, and sometimes gaming, so the S21 Ultra's advantages in those areas make it the better choice despite its higher price tag and older operating system (can be updated to 15). The overall user experience would be significantly better with the S21 Ultra for my personal needs. I do not require the dual sim + esim functionality that the Motorola provides. I would be willing to pay the higher price for a much better experience.
