I assume you mean the 70-200 and not "20-200". I am not a wildlife
photographer (I used the 100-400 for sports on an overcast day, the
horror!) but I will head up a local mountain with my 70-200 w/ 2x TC
and see if I can shoot some birds so we can compare apples to apples.
Remember, I did acknowledge the distortion as well as the softness.
Maybe my standards are lower. I guess we shall see.
Throwing the example of the 500mm f/4 in there is moot. 1) it is a
prime 2) it is a longer focal length 3) I was comparing 400mm f/5.6
to 400mm f/5.6.
