You pretty much nailed it. The only real reason for fast lenses nowadays is bokeh isolation. A secondary reason could be for opening up brighter on dSLR's to help see. For any other purpose, you generally get better image quality with a slower lens which has fewer/thinner glass elements inside.

So in F mount the 24-85, or 24-120 have better image quality than the 24-70E?

70-200F4 vs 70-200E?

200-500 5.6 vs 180-400 4?

While it can be argued that some performance is left on the table of the less expensive lenses by the designers, I think in the market today faster lenses tend to offer better image quality.
