My Choice

Given the above analysis, I would choose the Samsung Galaxy A42 5G. Although it is an older model, it offers significant advantages in areas that are most important to my typical use case: display quality, performance, and camera versatility.

The AMOLED display will provide a much more enjoyable experience for media consumption, while the more powerful chipset will ensure smooth multitasking and the ability to play most mobile games without issues. Additionally, the better camera system will allow me to capture higher quality photos and videos in a variety of situations. While the Realme Note 50 has a newer OS, slightly smoother screen and is cheaper, it sacrifices too much in other critical areas such as display, processing power, and camera capabilities.

For my personal needs, the Samsung Galaxy A42 5G is the more well-rounded and capable phone, even if it isn't the newest model and is likely to be found at a slightly higher price-point. The trade-offs on the Realme Note 50 (lower-quality display, slower performance and basic cameras) are simply too significant for my use case to be a viable choice.
