Really, it depends on what you are photographing. It also depends on how you see. Placing objects in perspective: wide angle. Simplifying down to essentials: long lens. Most recently I photographed in an aircraft museum, and needed the widest lenses. My 21mm was useful. Once in a while I might need the 90, but more often the 75 will do. But that's just me.
I think that the more extreme a lens is, the less it will be used. When there is no special requirement or constraint, a 24mm is usually wide enough for me. But then, I keep a 15mm and an 18mm around for the Nikons and at times I need them.
To go out photographing with no special goal in mind, I like to carry a 24, 35, and 75 as a three-lens outfit. Those are three well spaced focal lengths. I didn't vote because I didn't see that option.
