My Choice

If I were choosing between these two, I would go with the Realme 9 Pro.

Here's why:

As a tech journalist who appreciates both the technical details and real-world usability, the Realme 9 Pro offers a more compelling package. The Snapdragon 695 provides a noticeable boost in performance, which would ensure a smooth experience across various apps and games. The camera system, with its higher resolution and advanced features, is more versatile for capturing high-quality photos and videos in a range of conditions. Also, the 33W charging is a must have for my daily usage.

While the Motorola Moto G51 has a larger screen, this isn't a top priority for me. The more compact design of the Realme 9 Pro is also a plus. Most importantly, the added software support ensures that the phone will receive the latest OS upgrades. For someone who works with technology, these features and capabilities of the Realme 9 Pro are more aligned with my needs and preferences.

Ultimately, the "best" choice depends on individual needs and priorities. However, from my perspective, the Realme 9 Pro has the edge.
