No question for birds further away the 200-600 is way better of course. But for small fast erratic birds getting closer with a light fast lens delivers much better results for me.

Agreed. I too prefer the 100-400 over the 200-600 for close swallows. Even though for very close swallows both are beat by the 135GM (slower to AF but noticably better IQ for any hits).

I would far prefer to use the 100-400 even with the TC1.4 over the 200-600 whenever reach and light is not a problem. I just don't see the same kind of clarity from the 200-600 as these examples from the 100-400 show. As you can see reach was not a problem. Perhaps it is just my imagination but even horribly backlit images come out exceptionally well with none of the edge haziness and fringing I typically see with the 200-600.

I think part of what you are looking at is a poor-ish copy of the 200-600. Ignoring other differences, the IQ of those two lenses tends to be very close to each other. I've read lots of reviews and so far checked half a dozen 200-600 against my friends single 100-400: all pretty good except one copy, good copies are slightly better, poor copies are slightly worse, but the 100-400 with TC1.4 could only compete with the worst copy. This rtather matches what the majority of comparative reviews reported.

The secret to reach is here - much cheaper and lighter than a prime !

Absolutely.
