It might be a toss up with the larger aperture on the F2.8. My experience does not include comparing the two, but I have used the new FL version and it is possibly the fastest focusing lens I have ever used - coupled with a fast focus system like a D500, D850, D5 - I would guess than the F4 is fast, but the F2.8 may be faster. I wouldn't be surprised if the SW motor in the higher end lens is a bit beefier as well, just to move all that glass. It would be a mistake if it wasn't.
Yes, I should have qualified my statement with - "in good light" .....
