Like the pivot/fixed debate, it's all about what you want...
Brakes are applied by 12VDC solenoids inside the brakes.
Needs a controller (usually mounted in drivers position) and 12VDC to operate and the power wire between the Towed and Towing vehicle.
Most often drum style brakes.
Must be manually adjusted for load and brake wear.
Operation can be controlled (extra braking to no braking) by driver, at the controller.
A break-away device needs a battery on the dolly.
Applied by hydraulic pressure from the tongue mounted master cylendar (just like a car).
No extra pieces or parts used (self contained).
Fully automatic (operation and adjustment from fully loaded to fully unloaded).
Available in disc and drum style brakes.
Requires a lock-out to back-up (EZE-Tow comes with a lock-out key).
A break-away device is often just a pull cable on the master cylendar.
We have used both (electric on our old TT and surge on our boat trailer). Surge is much simpler to use, but slightly more expensive.
Some drivers like to manually engage Electric brakes to "keep the toad straight" on descents(?).
It's really a personal preference thing...both are good and do the job. BTW, there are many dolly's sold with no brakes. Brakes are not required by law on tow dolly's in some places...but obviously safer to have brakes
