What's more important to you, speed, or closeness? If it's speed, you can't do much better than cartridges, you just have to try a few to figure out which one works best for you. If you want a closer, and in many ways better, shave, then you need to try a single blade razor of some sort. I highly recommend injectors. They are the closest you can get to a cartridge razor, but you get all of the benefits of a single blade edge. DE razors are more common, and are what I, personally use most.
