RG-557 / One Pro
Verdict
One Pro has the strongest overall profile in this RG-557 vs One Pro comparison. One Pro leads the summary view with HR rating 71 and user rating 74. Its clearest measurable advantages are screen size (7 vs 5.48). Both land at about $249, 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.
