Re: R7 for wildlife/action; USM or STM?

My R7 arrives in a couple of days, and I am debating the 600mm f.11 (STM) vs. RF100-400mm (USM). Forgetting all other considerations (reach, f stop, weight, versatility, etc.), WHICH LENS TYPE would work best. Informed opinions welcome, actual experience invaluable.

I have the 800mm F11 STM. Works great on R6. On r7 it works well as far as AF speed and accuracy is concerned. The bigger challenge is the diffraction issue.

For me rf800 is for R6, rf100-500 for both R6 as well as r7.
