Trade-offs and Limitations:

  • Moto G51: The IPS LCD display isn't as vibrant as the Poco M4 Pro's AMOLED. Slower charging could be a pain point for some.
  • Poco M4 Pro: The 90Hz refresh rate is slightly less smooth than the Moto G51’s 120Hz. Missing a macro lens camera for the people who like detailed photography.

3. User Profiles and Recommendations

  • Motorola Moto G51 5G: Best for users who prioritize a large display for media consumption, prefer the feel of a smoother 120Hz refresh rate and need an additional macro lens camera. Also good for people who like additional storage and ram options.
  • Xiaomi Poco M4 Pro: Ideal for users who value a premium display, better performance, faster charging, and enhanced audio in a more compact and comfortable form factor. It's a great all-rounder with more modern technology.

4. Buying Decision Framework

Here are three key questions to consider:

  1. Do you prioritize display quality or a larger screen? If vibrant colors and deeper blacks are important, go for the Poco M4 Pro. If you prefer larger screen go with Moto G51.

  2. Is charging speed a significant factor? If you dislike waiting a long time for your phone to charge, the Poco M4 Pro’s 33W fast charging is a clear winner.

  3. Do you require large onboard storage and ram? If yes, then the Moto G51 would be the obvious choice.

Scenario-Based Recommendations:

  • Media Enthusiast: Poco M4 Pro for its superior display and enhanced audio.
  • Gamer: Poco M4 Pro for its faster chipset and GPU.
  • Casual User: Poco M4 Pro for its balance of performance, display, and charging speed.
  • On-the-go User: Poco M4 Pro for its lighter and more compact design.
  • Photography Buff: Moto G51 if a dedicated macro camera and additional camera features are essential.

My Choice

If I were choosing between these two, I would go with the Xiaomi Poco M4 Pro.

While the Moto G51's larger screen and 120Hz refresh rate are tempting, the Poco M4 Pro offers a superior overall experience. The AMOLED display is a game-changer for media consumption, the faster charging is a huge convenience, and the performance boost from the Helio G96 makes the phone feel snappier. I also value the additional audio quality and stereo speakers for my media consumption. For me, a premium display and faster charging are bigger daily wins than a slightly larger screen. Additionally I prefer a more compact design and the Poco M4 Pro offers that. The build quality with the Corning Gorilla Glass 3 on the M4 Pro also makes me feel like it will survive longer.

While the Moto G51 has some merits, for my usage patterns and what I seek in a modern smartphone, the Poco M4 Pro is the clear victor. It is the overall better package.
