Dell - Alienware m18 R2 vs Lenovo - Legion Pro 7i Gen 10

The Legion Pro 7i Gen 10 edges ahead on the Mars Score (81.9 vs 85.4), but the 3.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Alienware m18 R2 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 screen size.

Pick the Legion Pro 7i Gen 10 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are storage, refresh rate, claimed battery life, among others.

Both ship with comparable ram, cpu cores, panel type, 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.
