I agree with those who are saying that it depends on what you want it for. I bought a tank as my first kilt because I wanted to be married kilted. I wore it at my wedding and to the local a few times but not often and wore it less and less over the years.

I bought a UK and started being kilted more often, which has pushed me back towards getting more tailored garments. I think contemporary kilts are great starter kilts for daily kilting, but USAK & SWK are excellent for that too.
