You probably don't need another 'DP' wading in here, but what the hell...
Personally I'm somewhat between Oron's position and everyone else. One critical thing that everyone else has overlooked is that Oron indicates he was shooting Slog2 in AVCHD (or at least 8bit) and the camera really doesn't perform at it's best there.
Against a C300 - the C300 will generally produce more pleasing results, when shooting people. The colorimetry Canon utilises in both the C300 and 5D favours pleasing skin tones, while Sony is (supposedly) producing more 'accurate' colours (but these are not always too flattering). However the FS700 does genuinely have a touch more DR (at least half a stop, possibly 1 & 1/2), but you're generally not able to utilise it in 8bit (unless you like the low con Slog2 look). The FS700 is also better in low light (even without a speed booster) - the C300 is good, but the FS700 chip is insanely clean (despite the smaller sensor sites).
But that's AVCHD. Using the O7Q is a different matter. Shooting 4KtoHD Slog2 and using an ACES workflow I'd say the FS700 blows the C300 out the water. The extra DR gives a genuinely more filmic look, especially by controlling highlights and the 4K downscale makes it sharper, the 10bit colour gives you more latitude to colour correct (the C300 being 8 bit don't forget). But, Oron wasn't talking about 4KtoHD, as far as I can tell.
As for my 'go to' docco camera? In all honesty the FS700, C300 and Scarlet are equally as terrible as each other IMO. The Scarlet probably being the worst, due to it's unreliability, low-res viewfinder and hoodless monitor (both making focussing a nightmare), awful ergonomics, relatively poor low light performance and impractical (in terms of post and data rate) Raw codec. Likewise the C300 and FS700 have terrible ergonomics but they are at least reliable. Without the O7Q the C300 wins. With the O7Q it's the FS700 because it is better in low light and produces nicer, more flexible images (and the option of 4K and high speed makes it more flexible). The major downside being it's fragility as a system.
If I had to pick a camera, I'd probably go with an f900 in all honesty. S35mm is such a stupid frame size for docco work, as Oron indicates, due to the challenge of keeping unpredictable subjects in focus and the lack of long range, lightweight zooms. I'd say BM have been kind of smart offering a B4 sensor option with the Ursa. If I was forced to go S35 I'd pick an Alexa with a Cabrio 19-90 (but I'd struggle to convince the producer to pay for it). Those extra stops of DR (14!) plus great lowlight performance make a big difference. Although 90mm is still too short for docco work.
Oron's 100% right about the lenses. Stills zooms are god awful for docco work. Personally I end up using the kit zoom at f6.3 all the time (to avoid the exposure drop and to help focus) because 18-200mm is a workable range - but the servo focus, extending design and reverse zoom all do my head in. I'd kill for a half decent par focal, manual focus, internal zoom, lightweight lens with a fixed aperture (even a slow one: 5.6 would be fine). The Angeniuex 20-200 has the range but weighs an effing ton and costs a fortune!
