It looks like it may be a combination of a lower layer height, high quality filament, and possibly the way the picture is taken. (you could also have the layers start on the inside of the roller to prevent Z-scar from showing)
I'm not saying it isn't vapor smoothed ABS, but there are other ways to get that effect.
