Yeah, to be honest I actually had the same thought right after I posted that.
Teaching a new guy how to read a tape in imperial is far easier is more what I meant, 1/16th, 1/8th, 1/4s and 1/2s are all clearly indicated by the size of the lines while a metric tape is a bunch of tiny lines with no clear way to discern them making it harder on the eyes.
Aside from that though the smaller numbers just flow better and are less of a mouthful.
Metric is good for finishing mind you as its far more precise instead of trying to mark half way between an 1/16th and an 1/8th exactly the same multiple times when there's no clear reference point.
