4. Decision Framework

Here are three key questions a buyer should ask themselves:

  1. How important is display quality? If having the absolute sharpest, brightest screen is a top priority, the S21 Ultra is the better choice. The A54's display is still good, but not at the same level of detail or brightness, especially in bright sunlight.

  2. What is your primary use case for the camera? The S21 Ultra offers a more versatile camera experience with higher resolution, zoom capabilities, and 8K video recording, it also has better selfie camera quality and features. A54 is fine for everyday photos but lacks zoom and high end video quality, though it has an ultrawide and macro lens. Consider the DXOmark scores, A54 is better for video than the S21 Ultra.

  3. What are your preferences for size and ergonomics? If you prefer a more compact and lightweight phone that's easier to handle, the A54 is the better option. The S21 Ultra is bulkier and heavier, but offers a more substantial feel.

Scenario-Based Recommendations:

  • Scenario 1: High-Performance User: If you need the best possible performance, a superior display, and a versatile camera system, choose the Samsung Galaxy S21 Ultra 5G.
  • Scenario 2: Budget-Conscious User: If you want a well-rounded phone with good everyday performance, a comfortable design, and an ultrawide camera at a more affordable price, choose the Samsung Galaxy A54.
  • Scenario 3: Travel User: If your priorities include a good balance of performance, better video quality, comfort, and the ability to easily switch carriers with an eSIM, choose the Samsung Galaxy A54.

My Choice

If I were choosing, I would pick the Samsung Galaxy S21 Ultra 5G. My decision is primarily driven by the superior display quality, which is significantly sharper and brighter, making media consumption and outdoor use much more enjoyable. The enhanced performance is also a big plus, as it ensures a smooth experience for gaming and multitasking. While I appreciate the lighter design and newer software of the A54, the S21 Ultra's camera system, with its more versatile lenses, higher resolution sensors, and 8K video recording, along with the additional battery features, aligns better with my preference for high-quality imaging and professional-grade content creation.

Though the S21 Ultra is older, the premium features and the better display and camera make it a more attractive option if those features are prioritized. It's an overall higher-tier phone in terms of its hardware capabilities.
