If I were choosing between these two devices, I'd opt for the Oppo Reno8. While the Realme C51 offers a larger battery and attractive price point, the Reno8's significant advantages in performance, display quality, and camera capabilities are compelling. The Dimensity 1300 chipset ensures a smooth and responsive user experience, crucial for my workflow as a tech journalist. The AMOLED display's vibrant colors and sharpness are essential for reviewing visual content, and the superior camera system allows me to capture high-quality photos and videos for my articles. The faster 80W charging is a significant time-saver in my fast-paced life. While I appreciate the C51's value proposition, the Reno8's overall package aligns more closely with my needs and priorities. The performance difference alone would make a tangible impact on my daily usage.
