For what it's worth....
OEM Honda pads are thicker in the rear, and thinner in the front. Honda has a white spacer between the pad backing plate and the cage to prevent the heat from cooking the fluid. All the pads have the metal cage behind them.
EBC messed up when they first started making pads for ST's. They chose to cut corners and not include the spacer and or cage. They also decided to make one size fits all pads, thus thicker pads for both applications. What that does is not allow the Front pads to return to a rest position, and back away from the rotor. This causes the pads to ride the rotor, wearing both the pads and the rotors out faster, and always applying the rear brake due to the linked system. This is what causes the rear brakes to drag on most bikes.
That's just speaking about EBC, which is not a "no name" off brand. Those could be worse.
Given your brake are kind of important, and you don't want them locking up when riding, or not working when you need them, what's a few dollars more for OEM if you can afford it?
It's all about your level of acceptable risk.
