What I Would Choose and Why

If I were choosing between these two phones, I would choose the Asus ROG Phone 8 Pro. The reasons are multifold:

  1. Future Proof Performance: I want a phone that will perform at the highest levels for the longest period possible. The ROG Phone 8 Pro's newer and much more powerful Snapdragon 8 Gen 3 chipset, coupled with massive RAM and the Adreno 750 GPU, ensures that this phone will breeze through any task I throw at it for years to come. The S21 FE, while still capable, will start to feel its age more quickly.
  2. High Refresh Rate Screen: The 165Hz refresh rate on the ROG 8 Pro is a big draw for me. I value a smooth and fluid experience in every interaction, and the ROG phone provides that in abundance.
  3. Battery and Charging: The large 5500mAh battery paired with 65W fast charging is extremely attractive, minimizing the time I spend connected to a power source. While the S21 FE has wireless charging, this is something that I don't prioritize over fast charging.
  4. Versatile Use Case While I don't consider myself a hardcore gamer, I will find the ROG 8 Pro capable to handle all my heavy tasks, along with excellent quality video recording and image taking capabilities.

While the ROG Phone 8 Pro might not be as light as the S21 FE, or have a dedicated telephoto lens, the benefits far outweigh the drawbacks for my typical use case. It's the extra performance, combined with future proofing and the extra battery capacity that seals the deal for me. For someone looking for a premium device with maximum power, it is the clear winner.
