Main con: Bad drivers
I received the 9500 MKII today. My impression of the quality of the prints so far is good. However, the drivers are pretty poor (understatement when using on a Mac with LR) plus hard to find the icc profiles for the 3rd party paper etc. I am definitely not a fan of the LR printing module. I think I will try to print using CS or something similar.
A real big problem (for me) is the printer does not have an Ethernet port. I have no room downstairs, so have to plug it in using my Apple Time Capsule upstairs. The problem is, the Canon drivers do not like this very much at all. I had to install them on my Laptop and plug the printer in direct to align the print heads for example, as I could not do this using my desktop connected to the Printer via the Time Capsule. Also, I have no way of telling the ink levels unless I plug the laptop in direct. Hopefully this will be sorted out with a later driver release. Printing seems to be fine with the Time Capsule though, so not the end of the world.
Hopefully you will have an idea of the quality looking at the next 3 pictures. The scanner did not do justice to the colour of the print, as I can assure you it does match pretty much what I have on my screen. The scanner is not high quality….
This is the original:

This is the scan of the print:

This is a 100% crop of the scanned print:

I scanned at 600 dpi. I think I printed at 480 dpi. When you look at the print with the naked eye, it really looks fantastic. When you look at the hi-res scan at 100%, it does not look pretty, however, this is not a problem, as to the naked eye the picture is perfect.
Regarding the different colour of the scan, this is completely down to the scanner, not the print, as the colour was spot on.
So far I have only printed colour. No idea if B&W is any good yet....
