a LOT depends on the brake controller to be used. Many brake controllers sold today (timing ramp-up type devices) are so pitiful, they really aren't much if any improvement over a surge brake setup.
Unless you're willing to commit some $$ to purchase one of the really good electric brake Controllers (Tekonsha Prodigy, P3, or something like the MaxBrake that works directly off of brake hydraulic pressure)...IMO electric may not be worth the extra hassle of wiring it up. Surge brakes have come a long way over the years, and from what I've experienced, surge brakes work pretty good, especially in cases where the trailer weighs less than the tow vehicle.
I know this isn't relevant for the original poster here, but if you have one of the newer trucks that comes with an integrated brake controller...Its a no-brainer then, electric would be the only way to go.
