Steam Deck OLED vs ROG Ally X: Which handheld is better for everyday gaming?

Here is a realistic comparison based on real daily usage:

Choose Steam Deck OLED if:
- You prioritize instant sleep/wake (SteamOS handles this flawlessly like a console).
- You want 4-8 hours of battery on indies/emulators.
- You want deep black levels and HDR from the OLED display.
- You want trackpads for strategy games and cursor navigation.

Choose ROG Ally X if:
- You play Game Pass or anti-cheat games (Valorant, Fortnite, Call of Duty) that do not work on Linux/SteamOS.
- You want smooth 60+ FPS on demanding modern AAA games at 1080p.
- You need 24GB RAM and standard USB4 eGPU support.

For a 45-minute commute with indies and RPGs, the Steam Deck OLED is unmatched. The instant sleep/resume button alone makes it 10x more convenient than waking up a Windows device on a train.
