Neither is better or worse...just a matter of preference!
Bingo! You've hit the nail squarely on the head and driven it home.

Several years ago I commissioned a knife-pleat, which, at the time, was the only style of pleating I knew about. After a few more years of study, and a whole lot of X-Marksing, I chose to have my second kilt box-pleated. I then bought another box-pleat, because I liked it, and some time down the road, I have plans to design a tartan, and the kilt made from it will proabably be knife-pleated.

Which is better? The one I happen to be wearing at any given time.
