My Choice

If I were choosing between these two phones, I would personally pick the OnePlus 9 Pro. While the Honor 50 Lite offers some minor advantages like a potentially slightly better front-facing camera, side-mounted sensor, dedicated macro/depth sensors and faster charging and cheaper price, the OnePlus 9 Pro excels in almost every other crucial aspect that matters most to me: significantly superior performance, a much better display (sharper, smoother, brighter), more versatile camera system, and better battery features. The OnePlus 9 Pro's overall package provides a much more premium and enjoyable experience for my specific use cases, which involve gaming, photography, and media consumption, and the better screen experience is something I value highly. Though the price difference may be significant, the overall user experience and feature set of the OnePlus 9 Pro are compelling enough to justify it, for my usage scenario.
