Which should you buy?
The OnePlus Open 2 edges ahead on the Mars Score (74.5 vs 70.4), but the 4.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus Open 2 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are ram, screen size, battery capacity, among others.
Pick the Poco F7 Ultra if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are wired charging, weight, pixel density.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
