Olympus 300 Pro vs Sony FE 100-400

I am trying here a comparison of not totally dissimilar subjects but with dissimilar gear.

First Olympus E-M1MarkII + M.300mm F4.0 Pro image of American Bushtit :

Olympus E-M1MarkII + M.300mm F4.0 Pro @ ISO 250, FOCAL LENGTH 300.0 mm, APERTURE f/4.5, EXPOSURE TIME 0.0004s (1/2500)

Second Sony ILCE-9 + FE 100-400mm F4.5-5.6 GM OSS image of Jumiper Titmouse:

Sony ILCE-9 + FE 100-400mm F4.5-5.6 GM OSS (SEL100400GM) @ ISO 400, FOCAL LENGTH 400.0 mm, APERTURE f/5.6, EXPOSURE TIME 0.0004s (1/2500)

So, how do you assess IQ sharpness and feather detail, where in focus, in these two images?

K-H.
