Fuses are cheap and reliable, one time use, however they are typically more sensitive than breakers, and depending on the type, can have better time-current characteristics than breakers. Breakers are safer for residential occupancies as there are no shock hazards, you simply flip the switch instead of removing a fuse and exposing live electrical parts. Breakers are re-usable, and are less sensitive to voltage spikes which means they are less prone to nuisance tripping. With fuses, if a fuse blows, the typical homeowner replaces it with anything that fits (many times not the proper fuse, creating a fire hazard). With breakers you simply flip the switch again.
