A couple years back someone asked a similar question about which might be preferred lens to use in the overlap regions of the 14-30, 24-120 and 100-400, so owning all 3 and having a little bit of time on my hands, I stopped by a nearby college campus, set up a tripod and proceeded to shoot a quick comparison.
For my usage, any difference in these lenses in their overlap ranges is so insignificant as to have no bearing on which one I might choose to shoot a given scene with, so basically, the one I happen to have on my camera gets the call.
Here is a link to the photos from that effort.

All photos were shot on a tripod using a Z9 from the same location. A sunny day, but passing clouds did impact areas of the scene illumination, somewhat, in some of the shots.
I shot each lens wide open (or maximum aperture in the case of the 100-400), and also a f5.6 and f8) the files were uploaded to Flickr at full FX resolution, uncropped with 100% quality setting for jpeg conversion. Shot in standard profile with all settings in default.
These can be zoomed into for you pixel peepers. The photos are grouped by overlap range and by f#, so you can flip back and forth between like images at a given focal length and aperture. Also, I believe I have this album set to allow download of the full-size files for local viewing on your own display.
Cheers
