If you like the idea of keeping your paper towel dispenser out of sight, then a model that mounts to the inside of a cabinet door is probably the way to go. If you measure your cabinet doors and find that they are not wide enough to accommodate a standard holder and paper towel roll, then you could look into the models that hold the roll vertically. They are less common, and so a bit harder to find, but if they are the best solution for you, then it is worth the extra time and effort to find one.
