My Choice and Why
If I had to choose, I would personally go for the Realme 9i. Here's why:
- Display Quality: As someone who values a clear and crisp display for reading and media, the 9i's 1080p resolution is a significant win. I prefer a sharper display experience over a slightly larger one.
- Performance: The Snapdragon 680 chipset, while not the fastest, provides a smoother experience for everyday tasks. I would prefer the increased efficiency of the 6 nm architecture.
- Camera Versatility: While I do not take a lot of selfies, I often enjoy taking shots using a variety of lenses. Having additional macro and black and white lenses will be valuable to me.
- Audio Output: As someone who consumes a lot of media, the higher quality output will offer a more engaging experience.
While the Realme C51 has its strengths, the 9i strikes a better balance for my specific needs. The superior display, camera, and enhanced audio outweigh the newer OS and extra storage for me personally. However, if you need more storage, a newer OS out of the box, or you make a lot of calls then the Realme C51 will be better suited for your needs.
I hope this analysis has given you the information you need!
