Brice, the honest is it's hard to say, sorry!

Machine sewn kilts are different from hand sewn ones , certain things are easier to hand sew - like almost invisable fell stitching ( and matching up the lines) or blind stitching a hem , and certain things are easier by machine- like sewing through many layers at the waistband or long runs of straight sewing.

I've made both types and I tend to use a machine for the linen/cotton/canvas types which are usually 5 or 6 yard kilts, and hand sewing for the the more traditional wool 8 yard one. I can easily finish a machine stitched one of this type within a day's work from start to finish( including edge stitching all the pleat edges ,inside and out), but I wouldn't really compare it to the handsewn one ( not better - just different)
