As a user of command line Unix, and desktop computers since before mice were common, I use arrow keys and page up/page down. When mice became common, I used scroll bar more often. For speed, keystrokes almost always beat mouse movements. Surprisingly, only in the last few years did I really give the mouse wheel a try, due to a piece of software I was forced to use on a Chromebook. Now I use it frequently. Track pad or the little "pencil eraser" control on some laptops (in the middle of the keyboard) are my least used methods.
