My personal preference is to have the left buckle kind of hidden by the belt, and I definitely prefer 2 buckles on the right instead of one. Just my opinion though. I believe most of my kilts are that way so that's probably why I prefer it.

It's kind of like the "Did you grow up on Mac or PC?" debate. If you grew up on a mac, you prefer Mac's. If you grew up on a PC you prefer PC's. I just know what I'm used to.
