kit 14-42 or used prime wide such as Panasonic 14mm?

I have the 14, 20, 25, 45, 14-45, and 45-200.  I almost never use the zoom lens.  I do use the 45-200 for fall color during my fall trip to the N.C. mountains but that is about it.  If I knew what I know today, I would only have the 14, 25 and 45 mm lens.  The 20 quality is about the same as the 25 mm lens, but the 25 mm is tack sharp and nails the focus better than the 20.  Then the 20 is much smaller than the 25 so you have to judge for your self.  My 14 is soft around the corners if the subject is of the street taken from a distance.  Go to the museum and shoot glass or a painting and it is very sharp.  I think that the camera chose a smaller f/stop for the street shot where I set the settings for the museum shots at f/4 its sharpest setting.  I went to Chicago a year ago, and have several shots on my web page from Chicago.  The only lens that I had with me was the 25 mm lens.  The size of the 14 makes it easy to carry in a pocket to go along with that larger lens.  Don't really remember how fast the 14 was to focus.  It really is a lens that any prime shooter should have in his kit.

One thing about the primes.  when you go to look at reviews of people who are shooting with them, these fast primes are best when stopped down to f/4.  Bad for a zoom when that is nearest the fastest f/stop and you really need to stop down at least two stops from wide open.  Just not enough light for a fast shutter speed with a zoom.  That said, on a tripod that kit lens does a really nice job.  I just shot primes for so many years that it fits my style better.
