Dell - Alienware m18 R2 vs Lenovo - ThinkPad P1 Gen 7

The Alienware m18 R2 is the clear pick on raw spec strength, leading by 8.0 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

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 cpu cores, refresh rate, screen size, among others.

Pick the ThinkPad P1 Gen 7 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 claimed battery life, weight, thunderbolt ports, among others.
