I suspect the Nikon is a bit sharper, but superzooms have their weak points.

I've used an 18-200vr a lot over the years, on 10 and 12mp cameras.  (I've owned three of the lenses since 2007, one for me, one for my wife, and another that replaced my first one.)

Whichever lens you get, you should do some real testing before you take it on vacation to find the weak points.  You may want to avoid those weak points, or at least lower expectations when you shoot there.

For instance, the 18-200vr is quite good when used close up and more toward the wide end.   It's clearly weakest at long zoom - people have often said from about 135mm to 200mm.   I find it also weakest at long distances.   You'll want to know that if shooting a nice scenic and zoomed out - stop it down to where it gets sharpest.   Not sure if turning off VR would help it more or hurt there.

Here are some travel shots done with 18-200vr's my wife and I have taken. Should give some indication what to expect, but higher megapixel cameras could make the lens look worse, particularly if you crop much.
