While the Xiaomi Poco M6 Pro is excellent for budget-conscious users and provides superior battery life and outdoor display visibility, I prioritize raw power and camera flexibility over other features. The OnePlus 9 Pro would better fit my specific needs. The additional benefits of wireless charging and faster wifi are also valuable additions.
