I think that's asking a little much for one of these. Compared to a standard DSLR I think any of these mirrorless cameras are going to seem slow.
As far as the Sony, I had some bad experiences with their color reproduction early on in the digital era (particularly reds being too hot) and from what I understand they still have an issue with the colors.
Well... one can be fixed in PP, the other cannot
Not being able to focus in time is a massive dealbreaker for me. It's not like I'm asking for 7d-level tracking capabilities...
