4. Buying Decision Framework

  3. How important are camera quality and performance? The X100 Pro offers a substantial upgrade in both areas.

My Choice: I would choose the vivo X100 Pro. While it comes at a premium, the significant performance leap, superior camera system, stunning display, and blazing-fast charging make it a worthwhile investment for my needs. As a tech journalist, I demand a device that can handle heavy multitasking, resource-intensive apps, and capture high-quality photos and videos. The X100 Pro delivers on all fronts, offering a future-proof experience that justifies the higher price tag. The Realme 9 simply doesn't offer the performance or feature set I require.
