Alas there is no general rule

The way sharpness varies over the frame and at different apertures and focal lengths means that there's no way to make a general rule for this.

If you're asking will a prime lens get me more sharpness then in general the answer is no, IMO.

Sharpness is generally a result of understanding the importance of shutter speed and/or tripods and the performance characteristics of a particular lens at any give focal length and aperture. This combined with good understanding of depth of field and how the AF system works ( and when it doesn't work well ) are all important.

Modern kit zooms are generally very sharp and if you're not getting a sharp shot from them it's typically not the lens that's the problem.
