Hmmmm....

By its nature, a fish-eye is a specialty effects lens - no avoiding it.  Same as a tilt-and-shift or soft focus lens.  By definition and design it features a specific, repeatable optical distortion, which is an effect, and photographers manipulate and use this distortion to emphasize the subject or an aspect of the subject in interesting ways.

Per your observations, images made with a fish-eye lens can be post processed to make them more rectilinear, but resolution will always be sacrificed in the process.  The wider and more circular the initial image, the poorer the post-processed rectilinear image will be.  Its generally better to start with a good optically rectilinear lens in the first place.

I'm a little surprised that you only value the 8-15mm fish-eye as a post-processed rectilinear lens.
