Opinon needed on Oly 300mm F4 vs 100-400mm

From people that have owned both.

I now own the Oly 300mm F4 and both TCs. Mine is a very sharp copy and the dual IS is superb with my E-M1 II. About the same with the 1.4xTC.

However, I prefer zooms for convenience, and I am considering trying the Oly 100-400 F5-6.3.

So, my questions are...

How do the AF speed and accuracy compare with and without TCs.

How is the sharpness of the 100-400 at 400mm compared to the Oly 300mm + 1.4x?

How is the sharpness of the 100-400 at 400mm + the 1.4x TC vs the Oly 300mm + 2x TC?

How does the lens alone IS compare to the combined IS of the Em1 II + 300mm F4?

Thanks

Olympus E-M1
