Everybody here is likely to have different preferences in regard to brakes. We all have different bikes, with different power-to-weight ratios so different kinds of brakes will feel different on each bike. But if you're looking at stopping power: I like my new Sturmey-Archer drum brake that came with the HD front wheel I purchased from Pirate Cycles. It's easy to control the amount of braking force you want to apply, and FORCE is the operative word. It'll stop you fairly well. I imagine a disk brake would work pretty well too, but I don't know the brands well enough to recommend any.
