For sports and action shots that you are unable to close enough, I agree 1.3x APS-H gives the best balance of IQ and effective reach. 1D3 maybe old and only has 10mp but it still delivers one of the best skin tone with that creamy look more noticeable than my old 5D1 in certain cases even at ISO 1250. I am sure my 60D cannot match with that IQ, not only natural sharper but in creamy smooth color rendition. 1D4 is still a better option even over 1DX in birding as it has much higher pixel density while still generate excellent IQ till ISO 3200.





My 1D3 copy doesn't have AF issues as you might have seen in many of my airshow photos. I have no regret a bit to choose a lite used 1D3 over a brand new 7D and paid a few hundred more back in Oct '09. Even 1D3 no mention 1D4 is in a diferent league of AF, overall performance and IQ than 7D/XXD.

Canon flagship 1D/1Ds series have best low ISO IQ in Canon lineup, cleaner, creamier and much less banding if you pull shadow. After of all, Canon spent the best effort to generate as much good IQ as possible especially in low ISOs. 5D series are more compromised. 5D3 is the best in 5D series that closer to the respective 1D series (1DX in this case) in the same generation.
