The GKD Bubble and the Anbernic RG-353PS are priced within $2 of each other, share the same RockChip RK3566 chip, run Linux, and top out at PSP emulation, making this a comparison of design and build choices rather than raw capability. Both suit buyers after a capable entry-level device that handles systems up through PSP, so the decision comes down to which brand's button layout, screen, and build quality better fits your hands.
