A 3X fixed aperture zoom is theoretically going to outperform a 4X variable aperture zoom. My experience with 1.4X teleconverters is more positive than my experience with 4X zooms. But, like I said, I'm not a Canon guy so I'll bow out.
But even with Canon you are right here .. both lenses are supposedly very good pro lenses. But the 100-400 L is built for versatility, and the 70-200 L 2.8 is more built for image quality.
The 100-400 L is a bit soft at the 400mm end, at least the one I had in my hands. That is why I decided for the 300mm L 4. Also got a TC 1.4x now and will post images once I find some time to do so
From what I heard, the 70-200 L 2.8 is supposedly one of Canon's best telephoto zoom lenses. Of course primes are an alltogether different story.
