Nor will any be, when taken with that tiny sensor. Further, I was not suggesting that the P900 lens is more than "good". However, when I compare the best that I can do with a better camera and a shorter lens, the P900 usually wins. At distances where I can get a useful size image, my a6500 or my RX10 IV win. At the distances where the P900 is zoomed to maximum, there is no contest and the Nikon wins.
The attached screen capture is my full 1920 x 1200 screen viewing another P900 shot at 1:1 or 100% (terminology will vary). I don't see any motion blur. The EXIF says it was an equivalent length of 1600 mm. It was taken under the conditions and techniques I described earlier. I don't think it's particularly sharp but if you look at the reflection of the sun in the rabbit's eyes I think you will be hard pressed to see any camera motion. If there were, then there would be shape distortion (or more of it).
As a thought experiment, take the screen capture of the entire frame (it isn't cropped) and overlay a smaller rectangle representing 600 mm equivalent and see what you get. Then imagine how it would look enlarged back to the size produced by the P900. I have created a graphic to illustrate the relative size and crop. The blue background is a Full frame 8 x 6 box and the rabbit image is scaled on the wide dimension but retains its original aspect ratio. The blue area is what would have to be cropped on the full frame image taken at 600 mm. The image of the rabbit is the size you would need to crop to in order to equal the P1000's.
My view is that the P900 which costs about $600 is punching well above it's price on those long shots. As far as I know, the P1000 is as good and has the much greater reach if wanted. You can't even buy a decent 150-600 zoom for what the P1000 costs.
I'm not using a P900 and I'm willing to forgo shots that I can't get rather than accept the tiny sensor's limitations. But the image stabilization is good or better at zooms that other cameras can't produce. You can't expect that sensor to produce the sharpness we get from good cameras with APS-C or Full Frame sensors. But because of the extreme lens length, you can get good results at otherwise unworkable distances and with acceptable image stabilization.
Any camera is a set of design choices and cost-driven quality choices. This rant is just to put the P1000 in perspective and to assert that it's image stabilization is quite good for hand held shots in my experience.

Great image sensor graphic! Prior to digital cameras, nobody but 110 cartridge
camera or Minox owners had to worry about formats smaller than 35 mm.
That's progress!
But don't worry: the "high tech" digital sensor has
lower resolution per
unit area than good film. More progress!
People who wouldn't have dreamt of using a 110 catridge film (13 mm x 17 mm)
camera are now using digital camers with even smaller, lower-res sensors.
Sure, the image is poor, but the camera has a
computer in it. Oh boy!
And there's the tele zoom image in all its glory: flat as pancake, super-low
contrast. A scene dipped in gray paint and run over by a steamroller.
If your eye had 17 elements in 12 groups = 24 surfaces,
you wouldn't see any contrast either. But the eye if filled with
clear gel, so it has just
1 surface and can see about
10 stops of contrast at a time
And the only excuse for the long tele is to take a picture of a field
mousewithout having to figure out how to get close to it. Gee, my
cat canget close to a mouse -- close enough to bring it home and
leave it on the doorstep!
You know, there was a time when humans knew how to get close
enough to catch it for dinner. But now theyonly know how to buy
expensive lenses and cameras.
