Verdict
RGB20SX has the strongest overall profile in this RGB20SX vs X35S comparison. RGB20SX leads the summary view with HR rating 75 and user rating 94. Its clearest measurable advantages are screen size (4 vs 3.5). Both land at about $60, so the decision comes down to scores, ergonomics, and the specific specs you care about. For emulation, travel, and long sessions, weigh those score gaps against battery, screen, storage, and price rather than picking on raw ranking alone.

It's just misunderstood. The Powkiddy RGB20SX is a fun niche retro handheld, mainly because its 4-inch 720×720 square screen is excellent for Game Boy, Game Boy Color, Pico-8, and other 1:1-friendly games. Its RK3566 chip and 1GB RAM are fine for older systems, but it is not a great choice for heavier emulation, and the tall vertical body plus 4:3 black borders can feel awkward. Overall, it is a charming budget device around the ~$70–$90 range, but only worth picking over alternatives like the RGB30 if you specifically want the vertical form factor.
