The headline difference is the Vivo X300's 200 MP primary sensor, which dwarfs the Pixel 10 Pro XL's 50 MP main shooter. A higher megapixel count enables more detail retention when cropping and can improve large-format print quality, though real-world image quality depends heavily on sensor size and processing — neither of which is provided here. More practically, the Pixel counters with a longer 5x optical zoom versus the X300's 3x, which is a tangible advantage for telephoto shooting: 5x gets you meaningfully closer to a subject without digital degradation, making it the stronger choice for sports, wildlife, or distant architecture.
The feature set is broadly similar — both support OIS, phase-detection and laser autofocus, slow-motion, RAW capture, HDR mode, and 4K at 60fps. A few distinctions are worth noting, though. The Pixel includes a BSI sensor, which is specifically designed to improve light capture efficiency — an advantage in low-light conditions that the X300's non-BSI CMOS does not share on paper. The Pixel also supports manual shutter speed and HDR10 video recording, both absent on the X300, giving it a slight edge for users who want granular creative control or higher-dynamic-range video output.
This group is genuinely split depending on use case. The Vivo X300 leads on raw sensor resolution and front camera megapixels (50 MP vs 42 MP), while the Pixel 10 Pro XL holds the advantage in optical zoom reach, low-light sensor design, and video versatility. For telephoto and video-focused users, the Pixel is the stronger camera system on paper; for those who prioritize detail-rich stills and selfie quality, the X300 makes a compelling case.
