Lenovo - Legion Go S vs ASUS - ROG Ally Z1 Extreme

The Legion Go S edges ahead on the Mars Score (65.1 vs 60.7), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Legion Go S if you care most about storage. The biggest gaps in its favor are storage.

The ROG Ally Z1 Extreme similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

Both ship with comparable ram, max resolution, max refresh, 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.
