Surge brakes or electric ?

Which style is better for being in and out of saltwater? Thinking about putting brakes on 22ft tandem axle trailer hauling 21 ft boat

They make what they call electric over hydraulic. That uses a electric actuator that mounts to the tongue. Pretty pricey.I’ve had surge brakes on a 30-foot walk around for many years and have had no problems. I bought a kit from tie down (surge brakes) 3 years ago for my 22 ft bay boat. Very happy with them everything fit perfect took me about 2 1/2 hours to install

I am fragile.
