My Choice

If I were choosing between these two phones, I would pick the Nothing Phone (2). While I appreciate the compactness and durability of the S21, the sheer performance difference is a significant factor. The Snapdragon 8+ Gen 1 chipset in the Nothing Phone (2) would provide a smoother, more responsive experience that is important to me as I use my phone frequently for gaming and video editing, and would prefer to not experience any bottlenecks. The larger screen, increased brightness, and longer battery life are also significant advantages that I would prefer over the compact size of the S21. While the Telephoto lens of the S21 is an appealing feature, I would gladly trade it for the superior standard and selfie cameras provided by the Nothing Phone (2).

Additionally, the modern software and longer support cycle from the Nothing Phone (2) ensures that my device will be better supported for longer. Therefore, the Nothing Phone (2) better suits my needs as a power-user who also wants to take high quality photos, and am willing to pay a premium for the features.
