Either image quality is important, or it's not. In this case, it doesn't sound like it's that crucial (if it were, you would have stated the minimum quality needed).
Image quality is important. Our films are played to an assembled audience of up to 1000 people, and are frequently broadcast as part of a programme edit. And I do this at present from my 7D and T3i (and ENG and HDV)
I'm not going to composite. Beyond colour correction off my header qpcard reel I'm not going to grade anything.
Image quality is important.
Do I need RAW, no.
I'm just sorry I gave the impression that, as a professional cameraman, that image quality wasn't important.
If you've only shot with the 5D3 then maybe you aren't best placed to provide a helpful answer
And in terms of ease of use?
I've done the DSLR route, love the large sensor look for certain things. Hate the handling, hate the ergonomics, hate the cobbled on audio, hate the WB procedure. Nothing about what I shoot is about 'ease of use' it's about buying something designed for the job.
You say 'if I were a pro shooter'? What are you then? Shooting to show your pals on vimeo?
I'm not being chippy, but to throw in a line like 'Either image quality is important or it's not'...
..thats divisive and going to get a response.
