I have a feeling you're thinking I shoot people because I said Leaf, but actually, it's tabletop photography.
The reason I like Leaf better, is because every Phase file I've opened has been littered with color noise, at base ISO. Nothing that you can't get rid of with a little noise removal slider, and I've played with many settings in C1, I don't use defaults, but compared to Leaf, is the excessive chrominance noise because of heat? Kodak sensor? Don't know.
How is it that the leaf files were free of color noise, even in the deep shadows? Amazing. This was looking at both files in C1 with the same settings (I converted the leaf file to DNG and edited the DNG in a hex editor so that C14 could read it).
However, lately, playing with Lightroom, which I used to hate for Phase files, I've gotten perfect results from Phase files. I would honestly go with either back. In terms of sharpness and image size of course, it's hard to go wrong with any of these guys.
