I've looked at a lot of footage on different cameras trying to determine the answer to this question over the last few years. The reality is that there is no right answer. There are trade offs. You need to go out and find the look you like and not worry about whether it's 4:2:2 with 1 sensor or whatever. All these manufacturers make great looking camera images. You need to refine your questions. Are you shooting for TV? Web? Yourself? What is important to you? Do you work in teams? Or alone? interchangeable lens? Tele length? Depth of field? All in one camera for run and gun? What is your NLE?
All these questions will help determine the camera choice, and then you really really have to learn to use the camera. The choice of gamma, knee, on and on will mean way more than whether you are shooting on a CF card or SD card. I use both and it's really irrelevant. All these technologies are very very good. Better than our fathers ever imagined when they worked in the 50s with technology.
Go worry about your story, and the technology will reveal itself to you.
