What I would Choose and Why

If I were choosing between these two phones, I would choose the Samsung Galaxy S21+ 5G. While the Motorola Edge 30 has some appealing advantages such as its lighter weight, higher refresh rate and faster charging, the S21+ offers a superior overall experience that aligns better with my priorities and use cases.

Here's why:

• Performance: As someone who values smooth multitasking and gaming, the S21+'s Exynos 2100 chip provides a noticeable performance advantage that the Snapdragon 778G+ in the Edge 30 cannot match.
• Camera: The versatile camera system with its dedicated telephoto lens for optical zoom and 8k video recording capabilities makes it ideal for creative content capture which i value highly.
• Display: The significantly brighter display of the S21+ means much better visibility in direct sunlight which is crucial as I tend to be outdoors often. Although the S21+’s refresh rate is 120hz vs 144hz on the Edge 30, I believe the difference in real world use to be minimal.
• Battery and Wireless Charging: The larger battery ensures that the phone will last through a full day of heavy use. The wireless and reverse wireless charging capabilities are extremely convenient in my day to day use.
• Screen Protection: The use of Gorilla Glass Victus makes the phone more durable and less prone to damage, which provides peace of mind.

While the Motorola Edge 30 is a solid mid-range option, the Samsung Galaxy S21+ 5G offers a noticeable step up in areas that matter most to me, particularly performance, camera quality, display brightness and battery capabilities. This is why I'd be willing to invest the additional cost for the S21+ and choose it over the Motorola Edge 30.
