Apple - MacBook Air 15 M4 vs Microsoft - Surface Laptop Studio 3

These two are nearly even on the Mars Score (58.9 vs 60.7). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Surface Laptop Studio 3 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 ram, storage, refresh rate.

Both ship with comparable claimed battery life, panel type, thunderbolt ports, 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.
