I have both. Overall, the iQOO 15R is still comfortable for gaming even though it uses a new chipset. On the other hand, the display quality is still great for daily use, especially since the Poco X8 Pro Max screen still needs some tweaking. Overall, both are equally good for daily use depending on your preferences, but in terms of performance, the iQOO 15R still comes out on top, even if it means sacrificing device temperature.
