I never had a problem betting properly in focused shots if I did my job. All I shoot is sports and wildlife and I didn't find a significant difference in ai servo performance.
That is pretty much my experience, too. While I'm sure that the AF on my 1D Mark IV is (somewhat) better than that on the 7D, the difference is not so great that I feel like I'm compromising my ability to get the shots when I'm using the 7D. During the last month, when I've been using the 7D exclusively as I've tried to follow around and document the eagle fledgling that I've been watching, I've had numerous times when I've taken bursts of action shots with very busy backgrounds, and the only out-of-focus shots that I've had have been when I've failed to keep the selected focus point(s) on the subject. My shooting style is actually quite deliberate. Even when action shot opportunities crop up unexpectedly, instead of just raising the camera and firing away, I make sure I've properly locked in focus, and, if/when I sense that I've lost contact between the focus point and the subject, I back off and re-acquire focus, and, with that technique, the AF on my 7D has done everything I could ask of it.
When I choose between using the 1D Mark IV and the 7D, other factors besides AF become more important. When I'm focal length limited, the 7D is the choice. When I want portability and need focal length the 7D with my 400 DO is the choice. If neither of those two situations is the case, I'll generally choose to use the 1D Mark IV, but, again, when I do use the 7D, I don't worry about the AF letting me down.
And with regard to resolving detail in focal length-limited situations, that is where the 7D really shines. I know that, for the kind of shots that I want to be taking, I would not want to by using my 1D Mark IV unless I had at least a 500 mm lens available to me. And I would not want to be using a 1D Mark III or 1DX (which has pixel density similar to the 1D Mark III) unless I had at least a 600 mm lens available to me. Yet, the 7D gives serious reach with 400 mm. And I know that the kind of pictures that appeal to me involve shooting wider than many who who shoot wildlife. For those who like to shoot tighter, even more focal length is needed with a lower pixel density body. And, while I accept the fact that my 1-serious bodies have had advantages with things like build quality and ability to customize them, I have found nothing magical with regard to being able to get quality images besides the kind of snob appeal that one feels the need for after reading posts on internet forums.
I know that there are many whose skills as a photographer are at much higher levels than are mine, but, when I look at the high quality images that are being taken every day by people with the 7D, statements to the effect that you cannot take those high quality images with a 7D maintain no credibility whatever.
