  • For the Casual User: If your primary use is communication, social media, and browsing, the Realme C51 may be suitable, assuming there is a significant price difference between the two. However, note that its display is significantly inferior.
  • For the Photography Enthusiast: The Motorola Edge 30 Ultra wins hands-down. Its versatile camera system, higher resolution, and larger sensor sizes will result in far superior image and video quality.
  • For the Budget-Conscious: If there's a massive difference in price, the Realme C51 might be adequate for very basic usage, but expect a much less impressive experience overall.

My Choice

If it were my money on the line, I'd choose the Motorola Edge 30 Ultra every single time. Yes, it's likely more expensive, but the sheer gulf in performance, display quality, camera capability, and charging speed makes it a vastly superior device for anyone who truly values their smartphone experience. The Realme C51 is a basic phone and may be suitable only for very undemanding needs, if it is priced significantly lower. The Edge 30 Ultra isn’t just a phone, it’s a miniature, portable supercomputer that's ready for anything you throw at it.
