4. Decision Framework

Key Questions for Buyers:

  1. How important is raw performance (gaming, multitasking)? If performance is critical, the vivo X100 is the obvious choice.
  2. How much do you value wireless charging and eSIM support? If these are essential, the Samsung S21+ 5G has the edge.

Scenario-Based Recommendations:

  • Scenario 1: Budget-Conscious User: If the Samsung Galaxy S21+ 5G is available at a significantly lower price than the vivo X100, it could be a decent budget option, but be aware of the performance and display trade-offs.
  • Scenario 2: Power User: The vivo X100 is the better option for power users looking for top performance, fast charging, and a great display.
  • Scenario 3: Photography Lover: The vivo X100's camera setup, combined with its powerful performance makes it a better choice.
  • Scenario 4: Samsung Ecosystem User: If deeply invested in the Samsung ecosystem and needing the wireless charging or eSIM feature, then the Samsung Galaxy S21+ 5G remains a good choice.

My Choice

If I were choosing between these two phones, I would choose the vivo X100. While the Samsung Galaxy S21+ 5G offers some appealing features like wireless charging, the advantages of the vivo X100 are far more compelling in my opinion. The performance difference is substantial, which directly translates to a much smoother and more enjoyable user experience. Furthermore, the vastly superior display and advanced camera system makes the vivo X100 the clear choice for me. The faster charging and the larger storage capacity adds to the overall appeal. Even though I appreciate wireless charging, the 120W fast charging of the vivo X100 will make topping up the battery extremely quick, offsetting the need for wireless charging. The lack of verified screen protection on the vivo is a bit of a concern but not enough to make me choose the older and slower S21+. Ultimately, the vivo X100 offers a more complete and future-proof package.
