  • Scenario 1 (Performance-Focused): If you are a gamer or power user who prioritizes speed and graphics, the Samsung Galaxy S21+ 5G is the obvious choice.
  • Scenario 2 (Budget-Conscious): If you need a reliable phone for daily tasks and casual photography at an affordable price, the Samsung Galaxy A23 5G is the better option.
  • Scenario 3 (Multimedia Lover): If you enjoy high-quality videos, have to use the phone under bright sunlight, and value top-notch display, the Samsung Galaxy S21+ 5G is better.
  • Scenario 4 (Long-Lasting Battery): If longer lasting battery life is the priority over other considerations, the Samsung Galaxy A23 5G is better.

My Choice

If I had to pick one, I would choose the Samsung Galaxy S21+ 5G. My reasons are primarily based on the significant advantages it offers in display quality and performance. The AMOLED display with its superior brightness and color accuracy provides a much better experience for media consumption and general usage. The more powerful Exynos 2100 chipset ensures a smoother and more responsive experience, handling demanding apps and multitasking effortlessly. While the Samsung Galaxy A23 5G has a newer OS, a slightly better battery capacity, a wider variety of lens options, and a side fingerprint sensor, these benefits do not outweigh the S21+ 5G's overall edge in display, processing power, camera, and build quality. The inclusion of wireless and reverse wireless charging is also a plus, aligning with my daily usage needs. For me, the enhanced display quality and performance outweigh the trade-offs such as lower resolution selfie camera, and the potential lack of battery life compared to the A23 5G. The significantly better screen protection on the S21+ 5G is also important, as it is a crucial component of modern smartphones that often gets overlooked. In summary, the S21+ 5G offers a more premium, more enjoyable user experience.
