...........snip........... but somehow I always prefered the custom profiles in Photoshop.
Take all of this perfect skin tone, film like look in digital with a tiny, tiny, tiny grain of salt.
Do this. lay out a bunch of cameras, a Nikon, a Canon, a Phase, a Leaf, a hasselblad and shoot different scenes with different complexions.
Window light, direct flash, led, HMI, direct sun and tungsten.
Shoot dark African skin, medium brown brazilian, semi tan Russian and white translucent any nationality, especially Red Heads.
Then drop these files into C-1, Lightroom (any version), Photoshop (the last few versions) and all of their proprietary softwares, (depending on who owns who at the moment) and I can promise you that you'll go away scratching your head, or worse come to the conclusion that it's all subject, light, camera, ambient color, processor dependent.
I know because doing non scientific shooting everything looks different depending on the day.
We just finished one shoot with one model in 10 different settings, from rooms, to outside, to night scenes, window light, leds, hmi's, practical tungsten and you'd think the model was 5 different people.
So like most professional imaging, it always comes down to working an image deep in photoshop. The look from the processor is just that a preview look for clients to review on set or in web galleries.
In the cinema world I'd compare what a processor/camera does as a one light daily. Something for a client to chose an image from but nowhere close to where a final image will actually go.
I will admit that the newer versions of c-1 tend to produce the most pleasing skin tones and process faster, lightroom I feel has the most intuitive interface and I know little of Phocus but the skin tones I've seen in very limited testing looked really good.
Still, in the world of professional imaging, regardless of camera and processing, everything goes to photoshop for finish and everything that is finished well goes to a lot of layers in photoshop.
My suggestion, find the camera you like, the digital back/capture device you like, the processor that fits your workflow and don't worry about it.
Any pretty image can be made pretty. Any non pretty image can't really be saved.
So my point to the original OP is the same thing most people will tell you. Try what you want to buy and find what works for you most of the time. Nothing will be 100% but nothing ever is.
IMO

P.S. If you want to emulate film try exposure 2 or 3 from Alien Skin. Goofy name, great looks, though few of them can be applied and just run. Once again it takes a few layers.
