New zooms are much better. Superzooms now will have some vignetting and pincushion at some lengths. Old zooms had more chromatic abberation than prime lenses. Most zooms made in the past ten years are pretty decent, except for some of the super zooms.
I mostly use prime lenses as I like the bigger apertures and can zoom with my feet just fine much of the time.
If someone is too much of a snob to use a Nikon EDIF 80-200/2.8 AFS or a 70-200/2.8 AFS or 70-300 ED, I'll take it off your hands so you can have your credibility back.
