When I bought my first kilt, the kiltmaker advised me that there was one proper length and that was the middle of the knee. I thought the top of the knee length looked better but went along with the kiltmakers advice. With a little experience, I found that top of the knee was quite acceptable as well... and that's what I now prefer.

I put kilts that are too long (below the knee) in that same category as trousers that are too long.

But then - each to their own taste I guess.
