It's funny because although Kamen Rider is obviously gimmick driven, I'd always figure sentai would do better in sales since they had giant robots which I thought would sell much more readily than plastic locks with fruit on them.

Maybe the Locks are cheaper, and the giant robots are too expensive.

Rider is also the toyline that sells better with collectors. The thing with Rider is that the gimmicks are almost always alot more fun than the ones in sentai. The Rider toys are incredibly engineered.

Just take the wizard rings that activate a scanner in the belt and weapons PLUS the scanner powers a led inside the rings that makes them glow without using a battery.

Same with the Lock Seeds. The Toys are incredible in the way the sound interact with the sounds inside the belt and the weapons. Also the Rider Lock Seeds are full with unique sounds that pay hommage to the older henshin items.
