Similarly, if you wish to carry out a series of tasks on your computer (that one would usually do manually), and you need the clicker to click at exact positions, you should definitely try an auto clicker that has better accuracy and/or precision settings. For example if you want to play where the faster you click on the screen the more rewards you collect, then you should prioritize the speed options of the auto clicker over the accuracy.
While both these features are extremely important for your consideration, it really depends on what you make your clicker do.
