Brandon,
Don't lump all "plasma" cut capability in one category! There are entry level air plasmas that many use on CNC machines....then there are mid level conventional industrial plasmas....and on top of the performance curve are high definition class plasma. Further...the cnc machine and the z axis (torch height control) are critical to providing good cut quality on aluminum or any material for that matter.
Air plasma....on a machine with decent acceleration and accuracy, and a good height control system can cut aluminum very fast....but with typical cut accuracies in the plus or minus .025" range (sorry for the imperial measure)....where high definition plasma can hold tolerances down to .010", and will provide better metalurgy on the cut edge.
