The choice of the tripod head depends on what you use it for.
If you do landscapes and you want a tripod + head set that’s as light as possible, can be operated quickly and you don’t need extra precise framing, a ball head is the best choice. The main problem with the ball head is that once you loosen it, the camera is free to go in any direction —which is precisely why the ball head makes it so easy to reframe quickly.
The pan and tilt (or panoramic) head is the intermediate between ball head and geared head. The Acratech is the archetype, but Leofoto also makes an excellent model, which I have and use if needed:
As another contributor said above, you need a leveling base with this type of head.
Finally, the geared head, of which the Arca-Swiss Cube C1 model is the archetype, is heavy, bulky, slow to operate and not very intuitive until you really get to know it well. But it holds your camera and lens in place no matter what, there is no tightening to do, and it is splendidly precise. It is great to work slowly and deliberately, either in the studio or for architecture, old stones, etc. —basically all types of photography for which your subject is not about to run away from you.
