Which should you buy?
These two are nearly even on the Mars Score (75.1 vs 73.8). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Z70 Ultra 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 refresh rate, battery capacity, screen size.
Pick the OnePlus 13 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are wireless charging, front camera, pixel density, among others.
Both ship with comparable ram, main camera, 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.
