I can say from personal experience that the Tektro fork-mounted cable stop is a good one. It does allow you to change stem and bar configuration without changing brake adjustment (as long as you have enough cable housing slack), and my 750 had pretty severe brake judder without this hanger (which is the reason I installed it).
I have changed the brakes from the stock Shimano cantilevers (which use smooth post brake pads) to Tektro CR510s (which use threaded post brake pads). Setup is a snap with those and the brakes are very strong on this bike.
