I often use a wide variety of random generators because I need various ways to trigger ideas for characters and stories. Having these different ways of being able to create tales is useful. Mixing up what I use is also good for keeping me on my creative toes!
I see random generators as the modern equivalent of story cubes (I use those too!). I also use books of prompts (and have contributed to some), proverbs and well known sayings (sometimes I subvert these to generate even more tales) but, by far, the method I use most often is the random generator.
