Apple - MacBook Air 13 M4 vs Dell - XPS 13 (9350)

These two are nearly even on the Mars Score (60.1 vs 61.8). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the MacBook Air 13 M4 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 thunderbolt ports, screen size. The single most decisive one: Thunderbolt ports — 2.00 more. 2 vs 0.

Pick the XPS 13 (9350) 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, cpu cores, claimed battery life, among others. The single most decisive one: Storage — 100.00% more. 512 GB vs 256 GB.

Both ship with comparable ram, refresh rate, backlit keyboard, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
