Both the PowKiddy RGB20SX and X35H cost $60, run Linux on the same RK3566 chip, and top out at PSP-era emulation, so the choice comes down almost entirely to form factor. The RGB20SX, released April 2024, uses a vertical layout that suits Game Boy-style titles and shorter sessions, while the X35H, released January 2025, takes a horizontal orientation that fits naturally for systems like Super Nintendo or PlayStation. Neither has a hardware edge over the other.
