Yep it is a lot better My Brother looked at the specs it far exceeds his Present 1D Mark II and the MkIV, which I think was about £6k when he got it.
You cannot compare a Pro Body camera and the amateur market model SLR's let alone the Fuji they mention, the Pro Bodies, are just better made. For a start pick one up and you can feel how heavy it is. It will take the knocks, it's the same with Lenses, My brother has a Canon EF 28-300mm lens it is really well built and works day in day out where as cheaper lens such as Sigma gave up the ghost, the seals go, dust gets in etc.. Plus Canon have Pro Workshops where you can get anything fixed.
All the Pros I deal with are either Canon or Nixon.
You really need to be a pro to justify the outlay on this kit. and even then you keep it a long time!.
I would agree though that the actual difference to the naked eye, once you put it through Lightroom, Colour balance etc, View on a properly calibrated monitor, (you should not use a TN lcd for this) and then if you decide to print it through an ICC profiled printer etc is somewhat undistinguishable.
If you think that Canon is a lot have a look at
