I have used both and they are satisfactory on trailers used in fresh water environment. Disc brakes are easier to rinse when you use in salt water.

One thing about disc brakes is that the brake actuator uses the reverse light signal to deactivate the brakes when in reverse. You need a 5 prong electrical outlet instead of the 4 prong. If you have the standard 8/6 prong outlet you can purchase the adaptor at any trailer supply.

If I am going to replace a drum brake setup and I am keeping the trailer for a long time, I would go for the disc brake setup. You cannot use the same tongue actuator that you have for the drums on the disc brakes.

The disc brakes kit from West Marine is very simple to use to replace a drum brake kit. I would replace the brake lines at the same time.
