Yeah, extremes! Depends on your zoom...
With a lens like the 18-200 or the super-zoom compacts you'll be really using many focal lengths.
zooms make you lazy. If you see an object of your desire, you tend to just point, zoom and shoot. Whereas with a prime you have to go back and forth to fix the right crop and that has an influence on the perspective too.
So I've to constantly remind me when I have the 18-200mm mounted (almost all the time
) that I first fix the perspective (close=more depth, far away=flat) that I'd like and then use the zoom to do the cropping.
But if you're into reproducing a faithful real-life perspective, then you should use the 30mm prime, because when reproducing the picture at a 21" monitor or A3-printout at normal viewing distances, that should render the "viewport" almost lifelike...
