You cannot beat the pressure cooker for speed; it’s really the only way to cook most dried beans in less than an hour, and it’s usually way faster than that; presoaking is a waste of time if you use a pressure cooker.
However, there are three disadvantages: First, the timing is imprecise; this means you must open the device and check the progress, usually once or twice. Second, pressure-cooked beans sometimes disintegrate completely (adding salt from the start helps the beans keep their shape). Last, some beans, especially limas, chickpeas, and favas, create a great deal of foam when cooked. If they’re crowded into a pressure cooker, this foam can jam the valve and cause problems. As long as you don’t fill the pressure cooker more than half full, you need not worry about this.
Don’t bother to use the pressure cooker for very fast-cooking beans like lentils or split peas, which can go from done in about 5 minutes to overdone in 6.
