Both the PowKiddy X55 and the RGB10MAX3 share the same $90 price, RockChip RK3566 chip, JELOS operating system, and horizontal form factor, making them effectively siblings on paper. Both top out around PSP-era emulation. The practical differences come down to physical design details — screen size, button layout, and build choices — so the better pick depends on which fits more comfortably in your hands rather than any meaningful performance gap between them.
