Pick the Nord 4 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are weight, wired charging, screen size.
Pick the Xiaomi 15 Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are antutu, front camera, ram, among others.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
