My Choice and Why
If I were choosing between these two phones, I would choose the Samsung Galaxy S21+ 5G. My reasons are as follows:
- Performance is Key: As someone who uses their phone for many tasks, including occasional gaming and using multiple apps, the S21+'s significantly better processor, GPU, and RAM would result in a much smoother and more responsive user experience.
- Superior Display: The AMOLED screen with its 120Hz refresh rate and high brightness is something I wouldn't want to compromise on. I appreciate vibrant colors, smooth scrolling, and excellent outdoor visibility, all of which the S21+ offers in abundance. The A03 screen is a major downgrade in terms of both resolution and technology.
- Advanced Camera System: While the A03 has a higher megapixel count on its main camera, the S21+'s superior sensor, and multiple lenses (including telephoto and wide-angle), combined with its better video quality and stabilization, would be much more important to me. I often take photos and videos and prioritize the quality over quantity.
- Faster Charging and Premium Features: The 25W fast charging and wireless charging capabilities, which are not available in the A03, would be a major convenience for me. The S21+ also includes other features that I value, like a fingerprint sensor, better build quality, and stereo speakers.
While the S21+ would be the more expensive option and doesn't include a charger, the significantly superior performance, display quality, camera capabilities, and additional premium features more than justify the higher cost for me. The A03 simply makes too many sacrifices in areas that are important to my use case. I would be willing to invest more in the S21+ to have a much better overall experience.
