Which CCD is best?

Not talking about name brands here, I am talking about which CCD will be best for my needs. The actual chip

I am told that 2" per pixel is best, but if I am using a KAF8300 which has pixels at 5.4um and using the formula on Peter Ward's site s= (205 x pixel width)/focal length (mm) I will be getting 0.68" per pixel on the RC 8". Even the STL11,000 has pixels at 9.0um and this would still not give me 2" per pixel.

What I would like to know is this good or bad and why? Some detailed explanation would be preferred rather than short answers. I want to get my head around this issue and at present I cannot seem to understand why it should be a problem.
