Basically it comes down to the fact the C6 is the only i1 D3 derived meter on the market that has added display types using X-Rites native tools. We could do this because the C6 is a custom meter from X-Rite with a custom firmware.
Because of this we can store far more different display types into the meter than we previously could with any other kind of meter. The added display types increase accuracy for all display types because each one is more specific to the spectral output of the light engine.
The other big feature of the C6 is the dynamic exposure modes. It can be faster when doing so doesn't sacrifice accuracy and can extend read when it needs to.
On top of that are the goodies, the NIST Cert, the tripod extender and carring case. The NIST cert is one of those things that pro's need, home users not as much.
