For me agility is even more important that for most others as my main subject is flying dragonflies. Being able to quickly frametrack the subject with the camera/lens is very important and with big/heavy lenses like 2 kg or more this becomes very difficult. I love the Nikon PF concept but still waiting for the right ML camera to use it on
I would like a 4/300PF because the current F mount version has some IS problems that could be improved, and possibly native is slightly better for AF/IQ and slightly lighter than using an adapter. If Nikon doesn't make/plan a Z version (probably no need in the near future) I would buy the F version anyway and have to accept the IS limitations.
For the same reason I would prefer a 4.5/400 or maybe even a stellar 5.6/400. 4/400 might be on the heavy side judging from Canon 4/400 (way above Nikon 5.6/500PF in weight). Unless Nikon can loose a lot of weight compared to the Canon implementation (which I doubt) an f/4 400mm would probably be too heavy for me for "action" shots.
For me it is also important that both can be combined with a high quality 1.4x TC and have decent MFD. While I understand that bird photographers want a reasonably bright 500 or 600mm, I assume that Nikon can sell a lot more 300/400mm PF lenses with modest aperture because of much lower price and convenience out in the field.
