Very tough cameras to compare because the C100 is 1080P. I personally couldn't go back, even if I did like the C-line's form factor: which I don't - it's like the worst of ENG and the worst of DSLR mushed together.
Clientes have commented on th C100's images. They tendvto be clientes who work in marketing etc and have experience of seeing different cameras. The C100 is great for ease of use both filming and editing. It gets nice images without much fuss. In saying that for more mobile work I'm enjoying the Panasonics with IBIS and fast native lenses. I prefer the C100 look out the cam with minimal tweaking but for many jobs the Panasonic colours and look are fine. IMHO
