I've been an operator on a CET Q5 and a Vanguard...the vanguard was much easier to use, faster... The vanguard user interface on the rip computer was a lot simpler and more intuitive also. As for the print quality to be honest CET really couldn't touch vanguards clarity or resolution. Also the white ink and the vanguard didn't seem to get nearly as gunked up as it did in the CET.
