Electric over hydraulic brakes are a type of braking system on a trailer that utilizes a specific EoH actuator. It is essentially a mix between standard electric brakes and a hydraulic system.

A brake controller like the Hayes Genesis # HA81790 that you referenced that can work with both electric and electric-over-hydraulic brakes simply provides greater versatility, since it's compatible with both types of setups. A brake controller that's only compatible with electric brakes will not work with electric-over-hydraulic systems.

If your trailer just has standard electric assemblies and you don't ever foresee towing something different that has electric-over-hydraulic brakes then there's no particular advantage with this type of brake controller.
