  3. Budget: How much are you willing to spend for a premium smartphone experience?

Scenario-Based Recommendations:

  • Scenario 1: Tight Budget & Casual Use: If you're on a tighter budget, mainly use your phone for basic tasks, and prefer a slightly larger screen, the S21+ is a good option.
  • Scenario 2: Gaming & Power User: If you're a heavy gamer or need top-tier performance, and value a much brighter display, the S23+ is the clear winner.
  • Scenario 3: Future Proofing: If you want a phone that will stay up to date longer and offer software updates for longer, the S23+ is the better choice.

My Choice

If I were choosing between these two phones, I would pick the Samsung Galaxy S23+. Here's why:

While the slightly larger display of the S21+ is appealing, the performance gap between the Exynos 2100 and Snapdragon 8 Gen 2 is massive. I value the significantly faster processing speeds and better GPU offered by the S23+, as I prioritize smooth performance, especially for gaming and demanding applications. Also, the greatly improved brightness on the S23+ would be highly beneficial for outdoor use. Finally, the newer OS and additional software updates on the S23+ would provide a longer and more optimized user experience. While I would miss the slightly faster 8K video recording and a charger in the box, the overall benefits of the S23+ outweigh these minor trade-offs, making it a much more appealing option for my needs.
