    • OnePlus looks better, Realme is bigger but lower resolution.
  3. Are cameras important to you?
    • OnePlus wins hands-down with better sensors and extra lenses.

Scenario-Based Recommendations:

  • "I game and watch a lot of videos"OnePlus Nord CE 5G (faster, better display).
  • "I just need a phone for calls and social media"Realme C51 (cheaper, longer battery).
  • "I take lots of photos and videos"OnePlus Nord CE 5G (superior cameras).

Final Verdict: Which Would I Choose?

My Pick: OnePlus Nord CE 5G

Why?

  • Better performance (Snapdragon 750G vs. Unisoc T612).
  • Superior cameras (64MP main + 16MP selfie vs. Realme’s 50MP + 5MP).
  • Higher-quality AMOLED display (brighter, sharper, better contrast).
  • More RAM options (up to 12GB vs. 6GB).

The Realme C51 has a bigger battery and may be cheaper, but the OnePlus Nord CE 5G justifies its (likely) higher price with far better specs that make a real difference in daily use—especially for gaming, media, and photography.

If you can afford it, the Nord CE 5G is the smarter long-term choice. If budget is tight and you only need basics, the Realme C51 works—but expect compromises. 🚀
