DSLR and CCD chips

I'm curious to the real differences between the common DSLR chips (ie 350D /D70 etc) and smaller CCD - say DSI Pro.

They seem to have similar pixel sizes - all ballpark 7-8um....
DSLRs have much larger chip.

So - Both should capture a similar resolution image with any given telescope - right?
But the DSLR will capture a larger FOV.
The DSI pro (or other monochrome) - more sensitive due to no Bayer matrix - right?
CCD needs no mods for Ha imaging.
What about noise levels - I thought CCD had less??

Is this it in a nutshell?
