Sony - PlayStation 5 Slim vs Valve - Steam Deck OLED 1TB

These two are nearly even on the Mars Score (65.1 vs 62.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the PlayStation 5 Slim if you care most about max refresh and ray tracing. The biggest gaps in its favor are max refresh, ray tracing, disc drive, among others.

The Steam Deck OLED 1TB similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
