Print quality has a lot to do with X/Y accuracy, perhaps more than z-height (layer thickness). X/Y accuracy and a temperature controlled build chamber are why output from a Stratasys Mojo looks better than from a standard FDM/FFF personal printer, even though a Mojo lays down thicker layers than a lot of personal printers. An SLA printer like this one still lives by the same rules. Layer thickness doesn't matter if each layer is not laid down perfectly on top of the previous layer -- x/y variation is a quality killer.

In a nutshell, I'm saying you can't judge quality based on stats alone -- particularly z-resolution stats. Your eyes don't lie. You need to see prints.
