>>>>2650 LWPH in the centre at 200 mm, and people say it is pretty soft. But at the same time, this is pretty much the same as the 180-600, which most people say is a pretty good lens.

I can easily see the difference between 2650 lwpm and a lens that well above 3000 like the plena or the f14-24 in the centre. Its night and day.
On a 45mp sensor both of these two lenses (24-200 / 180-600) never look bitingly sharp. And do not resolve as much as the sensor can. And thats why I no longer have either. When usin a telephoto of an actual subject rather than a landscape I want the eyes sharp! And I mean sharp.
The example photos you showed as examples were either too small to judge at around 2000px at which point jamjar bottom looks sharp, and some over sharpened which looks worse that just accepting a softer image.
I have the 100-400. Its great from 100 to 300. Its VISIBLY worse at the long end above 300mm. Its still slightly sharper than the 180-600. And its a good lens. I have the 135 plena which really is sharp corner to corner esp at f2.8. It can out resolve the sensor easily. The 24-120, is almost as sharp at the widest two apertures in the centre albeit at f4. But visibly worse at the edges or corners.
If you cant see the same thing than I do not know what you are looking at. To judge sharpness you need to look at an unsharpened raw file. And compare with a truly sharp lens. Those need no sharpening or almost non. But thats why they cost so much...
If on a smaller mp sensor the difference are harder to see. Because the resolution isnt as high to start with. And this stuff only matters if you care about it.
