    • If no, the Moto G51 could work fine if you are on a budget.
  2. Is display size or portability more important?

    • If display size, the Moto G51's larger 6.8" screen is ideal.
    • If portability, the Moto G55 is a lighter and more compact design.

  • The Photography Enthusiast: The Moto G55 is slightly better in low-light and has features like video stabilization, but the Macro camera in the Moto G51 could be a deciding factor for some.

My Choice

If it were my money and I had to choose between these two phones, I would definitely go for the Motorola Moto G55. While I do appreciate the larger screen and the macro camera in the G51, the advantages of the G55 are too significant to ignore. The faster processor, better camera performance, superior battery charging, and a much newer OS make it a more well-rounded phone for daily use. Also, the better GPS accuracy is a must for my long drives. The improved build quality and stereo speakers are also big pluses for me. The G55 is more future-proof and delivers a smoother experience overall.
