# Factory World vs Idle Light Bulb

Factory World and Idle Light Bulb both sit at 4.7 stars, but that hides the real split: 82% of Idle Light Bulb's written reviews are positive against 31% of Factory World's. Factory World's advantage is ratings volume (25K vs 3.3K). On price, rating, update cadence and ads there is nothing between them.
